Overview What Is It?
Breastfeeding is one of the best ways to ensure your baby's health and development. It's a convenient, cost-effective, natural way to feed your baby.
Breastfeeding is one of the best ways to ensure your baby's health and development. It's a convenient, cost-effective, natural way to feed your baby.
Breastfeeding is widely recommended as the best way of feeding infants by leading health organizations, including, among others:
Healthy mothers should consider breastfeeding exclusively (no formula) for the first six months of life and, if possible, continue until the baby is one year old and beyond. Ideally, solid foods should only be introduced after six months of age.
While most new mothers breastfeed in the weeks following birth (called the early postpartum period), less than 15 percent continue to nurse exclusively through six months. The likelihood of breastfeeding is even lower among African-American women, as well as women with lower levels of education.
Initiatives to educate new mothers and their partners, health care professionals and employers about the clear, long-lasting health benefits of breastfeeding for both mom and baby are ongoing. Changes to routine maternity unit practices, including "rooming in" policies, which allow mom and baby to stay together in the hospital, are increasingly common and help support mothers who wish to breastfeed. Healthy People 2020, a national prevention initiative to improve the health of all Americans, set forth goals to increase breastfeeding rates.

Diagnosis
Breastfeeding is a natural and rewarding process; however, it can be harder than it looks. If you have trouble breastfeeding, contact your health care provider or consult a lactation consultant or counselor. Breastfeeding challenges are often easily overcome with some support and, occasionally, treatment, so don't give up.
What's a Lactation Consultant?
Lactation consultants are professionals who are trained to help mothers who want to breastfeed their babies. Most hospitals and clinics have lactation consultants on staff to help new moms learn to nurse. They can provide encouragement and assist moms and babies with latching difficulties, painful nursing and other issues that may interfere with efforts to breastfeed. To find a lactation counselor near you, visit the La Leche League's website: http://www.llli.org.
Common Complications with Breastfeeding
There are several problems new mothers may experience when breastfeeding, including:
Treatment
There are ways to treat or prevent problems that may develop because of breastfeeding. Even if you begin to have symptoms like sore nipples or other issues, it's important not to give up before speaking with your health care professional or lactation consultant—or even a friend who has successfully breastfed her children. Here are some treatment options for the most common breastfeeding symptoms.
Sore Nipples
To treat or prevent sore, cracked nipples:
Nipple soreness and chapping should go away within several days. If it doesn't, you should contact your health care provider or lactation consultant.
Engorgement
If your breasts are engorged (overly full), breastfeed frequently to help empty your breasts and relieve fullness and pain. If this is too painful, try to manually express some milk to provide a natural, soothing lubricant. This may also make it easier for the baby to latch on to the nipple. To ease engorgement, take a warm shower or apply warm compresses for a few minutes before breastfeeding. If your baby is not latching on well, use a pump to reduce engorgement and help your milk flow. Use cool compresses between feedings to reduce swelling.
Plugged Milk Duct
This is a common problem for many breastfeeding mothers. Treatment may include: getting extra sleep or rest; applying heat compresses or taking a hot shower; massaging the blocked milk duct toward the nipple during nursing; and breastfeeding from the affected breast to help loosen the plug. Applying cool compresses to your breasts after feeding may also help.
Mastitis
If you suspect mastitis, or a breast infection, you should consult your health care provider right away. He/she will prescribe antibiotics and may recommend an analgesic to relieve the pain. Hot showers or compresses before breastfeeding can help by increasing circulation to the affected area.
In most cases, you can continue nursing through breastfeeding problems, even an infection. Emptying your breasts frequently can often reduce inflammation and relieve the problem.
Prevention
Breastfeeding is a unique experience for each woman and her baby. You may not experience the same (or any) breastfeeding symptoms a friend had, while you may have more trouble getting started than your mother did (or not). Many difficulties associated with breastfeeding can be minimized. The benefits of staying committed, whenever possible, to breastfeeding always pay off.
Here are a few tips to further explain why breastfeeding is valuable to you and your baby's health now and in the future, as well as how to prevent complications.
Facts to Know
Questions to Ask
Review the following Questions to Ask about breastfeeding so you're prepared to discuss this important health issue with your health care professional.
Can you recommend a lactation consultant? Are there support programs for new mothers?
How often should I breastfeed? How will I know whether my baby is getting enough milk?
When should I introduce a bottle?
How can I prevent sore nipples?
Can I continue breastfeeding my baby if my breasts are sore or if I have a cold or the flu?
Are there specific foods I should eat or avoid eating while breastfeeding? What about alcohol or caffeine?
Are there any over-the-counter or prescription medications that I should stop taking?
I've heard that I can't get pregnant if I'm breastfeeding. Is this true?
What should I look for in a breast pump?
How often should I pump when I go back to work?
Can I exercise while breastfeeding? How will this impact my milk supply?
How can I minimize leakage from my breast?
Key Q&A
How often should I breastfeed?
Babies need to be breastfed frequently and until satisfied. This may mean breastfeeding eight to 12 times a day or more for about 15 to 20 minutes at each breast. Let your baby determine the feeding schedule (otherwise known as nursing on demand). Watch for early signs of hunger, which include:
• Increased alertness or activity
• Mouthing or putting hands to mouth
• Rooting (moving his/her head in search of your nipple)
How long should I breastfeed?
Babies should be fed with breast milk only—no formula—for at least the first six months of life. It's important to continue breastfeeding for as long as you can, ideally until your baby is one year old or beyond. The longer you breastfeed, the greater the health benefits for you and your baby.
How do I know if my baby is getting enough milk?
Many mothers worry about whether their babies are getting enough milk. An easy way to gauge whether your baby is getting enough is to pay attention to his/her weight and the number of wet and dirty diapers. This may include:
• Consistently gaining weight after the first three to seven days after birth. Babies often lose some of their weight (about 7 to 10 percent) within the first week.
• Six to eight wet diapers and three to four yellow, seedy bowel movements by day five.
What is colostrum?
Colostrum, also called "first milk," is a thick, yellowish fluid that helps your newborn's digestive system grow and function. Even though it looks like a small amount, this is the only food your baby needs until your milk supply comes in, usually within five days of giving birth. Colostrum is rich in nutrients and provides protection against infectious diseases. Because colostrum is so nutrient rich, a very small amount is an entire feeding, so new mothers should not doubt that they can supply their babies' needs.
How do I know if my baby has latched on properly?
If your baby has latched on correctly, he/she should have your entire nipple and most of the areola (the dark skin around your nipple) well into his/her mouth. Make sure your baby's whole body is turned toward your breast, not just his/her head. Try positioning a pillow just below your breasts to ensure the baby is resting comfortably at the same level as your nipple. Your baby's suckling should be even, and you will hear his/her swallows.
Should breastfeeding be painful?
No. Although you may experience some discomfort and tenderness during the first few days, breastfeeding shouldn't be painful. You may feel the slightest tug or pressure sensation. If breastfeeding hurts or you have flu-like symptoms (fever, chills, feeling run down), contact your health care provider.
What is a lactation consultant?
Lactation consultants are professionals who are trained to help mothers who want to breastfeed their babies. Most hospitals and clinics have lactation consultants on staff to help new moms learn how to nurse. They can provide encouragement and assist moms and babies with latching difficulties, painful nursing and other issues that may interfere with efforts to breastfeed. To find a lactation consultant near you, visit http://www.llli.org.
What is the let-down reflex?
You may experience a tingling or tightening sensation (some women describe it as a pins and needles sensation) as your milk lets down and fills your breasts. This reflex means your milk is ready to flow. This sometimes occurs in response to your baby's cry or when a feeding is overdue.
How can I maintain my milk supply?
Your milk supply will respond to your baby's needs—the more your baby suckles, the more milk will be produced. If you're concerned about your milk production, increase the number of feedings a day. Other steps to take include:
• Pumping when you return to work or plan to be away from your baby for an extended period of time
• Getting plenty of rest
• Eating a nutritious diet with plenty of calcium
• Delaying introducing formula or solid foods until six months of age at the earliest
Are there foods or medications that I should discontinue while breastfeeding?
Pay attention to foods that might bother your baby. If you notice a pattern, avoid the food for a few days and then reintroduce it to see what happens. Most mothers who eat a balanced diet and don't have a history of allergies won't need to restrict the foods they eat, except for a few things. Caffeine and alcohol can get into your milk, so limit their intake. You should also avoid certain kinds of fish and shellfish high in mercury; these include shark, swordfish, king mackerel and tilefish. You can safely eat up to 12 ounces (two servings) a week of fish and shellfish low in mercury, including shrimp, canned light tuna, salmon, pollock, clams, haddock, trout and catfish. Some medications may be harmful to your baby if they pass into your milk. Be sure to check with your health care provider about which foods, beverages and medications are safe for you and your baby.
Can I continue breastfeeding when I return to work?
Yes. A growing number of new moms are returning to work and can continue breastfeeding thanks to breast pumps and storage containers, as well as policies that encourage workplaces to be supportive of nursing. Pumping can help you maintain your breast milk supply and keep you connected to your baby, even when you are away. Employers benefit because breastfeeding moms often need less time off for sick babies.
How long can I use stored milk?
The following are some guidelines for freshly expressed breast milk storage from the FDA and the CDC:
• At room temperature (66–72°F) for up to 10 hours
• At 72–79°F for four to six hours
• At 86–100°F for up to four hours
• In a refrigerator (32–39°F) for up to eight days
• In a freezer contained within a refrigerator for up to two weeks
• In a self-contained freezer unit for three to four months
• In a deep-freezer (0°F) for six to 12 months
What are the most recent guidelines for pregnant and breastfeeding mothers about eating seafood?
Some fish contain high levels of mercury that can harm your baby's developing nervous system if eaten regularly. However, a recent federally funded report released by the Institute of Medicine (IOM) showed that the heart benefits of seafood outweigh the risks. The report showed that omega-3 fatty acids found in fish promote healthy vision and brain development in infants whose mothers consume seafood while they are pregnant or nursing.
So does this mean you should eat fish or not? The answer is you should eat fish, but you should make sure it's the right kind. Guidelines issued jointly by the U.S. Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) note that pregnant women can safely eat up to 12 ounces (about two servings) a week of a variety of cooked fish and shellfish with lower levels of mercury, such as shrimp, clams, oysters, salmon, catfish, crab, haddock and trout. If you choose tuna, stay away from albacore, or white tuna, which contains higher levels of mercury than canned tuna. The FDA and EPA also recommend that women of childbearing age, pregnant women and breastfeeding women not eat shark, swordfish, king mackerel or tilefish, which have high levels of mercury.
In addition, they recommend that you check local advisories about the safety of fish caught by family and friends in your local lakes, rivers and coastal areas at www.epa.gov/waterscience/fish. If no advice is available, eat up to six ounces (one average serving) per week of fish you catch from local waters, but don't consume any other fish during that week. And as always, talk with your health care professional about the risks of eating fish and shellfish while breastfeeding. For more information, visit the FDA's food safety website at www.cfsan.fda.gov/seafood1.html.
Lifestyle Tips
Similar to when you were pregnant, it's important that you lead a healthy lifestyle. Make the right choices for you and your baby:
Problems are common during the beginning stages of nursing. Although it's a natural process, breastfeeding is also an art. Take your time and try not to get discouraged or overly stressed, which may make it worse.
Ask for help if you need it. Lactation consultants can offer encouragement and help you overcome difficulties. You may also want to find out about new mom support groups. Talk openly with your partner and family about how they can be supportive of your efforts to breastfeed.
Health Benefits
Health Benefits for Mom and Baby
There are compelling reasons to breastfeed—and both you and your baby benefit.
For Your Baby...
For You...
Breastfeeding saves time and money. There are no bottles to sterilize or formula to mix or warm. In fact, families save an estimated $1,000 to $2,000 on formula per year. In addition, mothers who breastfeed pay fewer out-of-pocket health care costs and take fewer sick days because breast-fed babies are healthier and tend not to need as many visits to their pediatric provider.
How the Breast Produces Milk
Milk production is a normal physiologic response to the childbearing experience. New studies shed light on milk delivery, the composition of milk and the anatomy of the lactating breast. This information can help new moms better understand their bodies and how they respond to breastfeeding.
After pregnancy, your breasts produce colostrum—a thick, yellowish fluid—that helps your newborn's digestive system grow and function. Colostrum, often called "first milk" or "immune milk," is rich in nutrients and infection fighting antibodies. While you may wonder whether you're producing enough colostrum or milk for your baby in these first few days, keep in mind your baby's stomach is only the size of a marble. Your mature milk supply typically "comes in" within five days of giving birth.
When you put your baby to your breast, your milk doesn't automatically start to flow. Your body responds to your baby's suckling patterns, which occur in two phases.
Anatomy of the Lactating Breast
New research using ultrasound imaging reveals a number of key differences from the previously held understanding of the anatomy of the breast. These findings can help mothers understand how their infants obtain milk and provide insights for physicians and women considering breast augmentation or reduction surgery.
Key findings include:
The absence of lactiferous sinuses changes our understanding of the way in which the breast produces and delivers milk. For example, it's thought that the lack of lactiferous sinuses is a reason why little milk is able to be expressed prior to milk ejection. Much more study needs to be done to further understand milk delivery.
The number of milk ducts also has implications for breast augmentation surgeons, since the loss of only a few ducts could seriously compromise a woman's ability to breastfeed. The overlapping of fat and glandular tissue also suggests that it is very difficult to remove only fatty tissue from the breast.

Challenges & Support
Overcoming Breastfeeding Challenges
Breastfeeding is a natural and rewarding process; however, many women have trouble during the early stages of nursing. The good news is that most of these problems can be resolved with patience, practice or treatment.
Don't be discouraged if you experience sore nipples, engorged breasts, mastitis or thrush. The severity of these symptoms can vary, but they all are treatable and often avoidable.
Breastfeeding shouldn't hurt. Contact your health care professional if your breasts remain tender or sore, or if you have flu-like symptoms that may indicate an infection. In most cases, you can continue breastfeeding. Emptying your breasts frequently by breastfeeding or pumping can often reduce inflammation and relieve the problem.
Finding Extra Support
Your health care professional may suggest that you work with a lactation consultant (also called a lactation counselor) who can review breastfeeding techniques and help you address any problems that you may have while nursing. Many hospitals and health centers have lactation consultants on staff, so make sure to ask your obstetric or pediatric provider if you think you need extra support. New mother support groups and encouragement from your partner, family, friends and employer are also important.
When Not to Breastfeed
Despite the clear benefits of breastfeeding, there are circumstances when breastfeeding is not in the best interest of the baby. A woman should not breastfeed if her infant is diagnosed with galactosemia (a rare metabolic disorder) or if she has certain health conditions that can be passed to her baby through breast milk, including:
Mothers who use illicit drugs, drink excessive amounts of alcohol or are taking prescribed chemotherapy or radiation therapies for cancer also should not breastfeed. If you have a herpes lesion (sore) on your breast, you should not breastfeed.
Women who have had breast reduction surgery or breast implants may not be able to breastfeed because of the impact these surgeries can have on milk production. However, each woman's breast anatomy and breast surgery is unique, so in many instances it is possible for a woman who has had this type of surgery to breastfeed. Discuss any concerns you may have about your ability to breastfeed or complications you may experience breastfeeding with a lactation consultant.
10 Hints for Ensuring Success
Start early. Learn as much as you can about breastfeeding before your baby is born so you'll feel prepared. Try to breastfeed your baby soon after giving birth (within the first hour). Newborns sleep a lot, so you may have to wake him/her every couple of hours for a feeding. Ask to keep your baby in your hospital room (called "rooming in"). Mother-infant rooming in is becoming more accepted as hospitals try to support early breastfeeding.
Review nursing techniques with a lactation consultant or nurse. Learn how to position your baby to properly latch on to your breast. This will improve your confidence when you return home.
Nurse frequently (8–12 times in 24 hours) and anytime your baby seems hungry. Your milk supply responds to your baby's demand—the more the baby suckles, the more milk will be produced. Many health care providers recommend breastfeeding on demand rather than according to a predetermined schedule. Watch for early signs of hunger, which include:
• Increased alertness or activityBe aware that crying is a late sign of hunger. Try to feed your baby before he/she becomes overly hungry and starts to cry. Offer both breasts during feedings. Usually breastfeeding takes 10 to 20 minutes for each breast. However, from time to time your baby may become full after feeding on just one breast. If this is the case, remember to pump the breast that remains full to avoid engorgement or discomfort. Your baby will empty the first breast it nurses at more completely than the second breast, so make sure that you alternate which breast you begin nursing with at each feeding.
Know how much milk is enough. Many nursing mothers worry about whether their baby is getting enough nourishment. An easy way to gauge whether your baby is getting enough milk is to pay attention to the number of wet, dirty diapers (six to eight wet diapers and three to four yellow, seedy bowel movements by day five are good signs). Keep in mind that it's normal for babies to lose some weight (about 7 to 10 percent of birth weight) within the first week. If you are still concerned about whether your baby is getting enough milk, seek the advice of a health care professional or lactation consultant. Also keep in mind that babies are born with a special supply of fat (called brown fat) that only newborns have. This fat is meant to sustain the baby until its mother's milk comes in. Between this fat supply and your colostrum, baby has no need for supplemental feedings.
Choose a comfortable position. Breastfeeding is very personal. There are a number of ways to hold your baby while breastfeeding. See what feels most comfortable for you and your baby. (See the American Academy of Family Physicians Web site for more information.)
• Cradle position: Place your baby's head in the crook of your arm. Support his/her back and bottom with your arm and hand.No matter which feeding position you use, make sure your baby's whole body is turned toward your breast, not just his/her head. Your baby should have your entire nipple and most of the areola (dark skin around the nipple) well into his/her mouth.
Breastfeeding shouldn't hurt. If you feel pain or discomfort, your baby is probably not latched on properly. Gently place your finger into your baby's mouth to break the suction and try again. You may want to position a pillow just below your breasts or under your arm to support yourself and ensure the baby is at the same level as your nipple. Contact your health care professional if the pain continues or if you notice flu-like symptoms.
Take care of yourself. Get plenty of rest and eat well-balanced meals to regain energy. A good rule of thumb to make sure you are taking in enough fluid is to have something to drink each time you nurse.
Ask about medications. Talk with your health care providers about any prescription medications or over-the-counter drugs or herbs you are taking just in case these may be harmful to your baby.
Refrain from giving your baby other liquids or formula during his/her first six months.
Delay introducing bottle nipples or pacifiers to let your baby develop a good sucking pattern and become familiar with feeding from your breast. If you plan to return to work, try introducing a bottle filled with your breast milk during week three to six (depending on how soon you plan to go back), after breastfeeding is well established.
Returning to Work: Breastfeeding Tips for Working Moms
The transition back to work after maternity leave can be emotional. You're probably asking yourself lots of questions: Can I overcome the guilt of leaving my baby? Will I be able to juggle motherhood and work? How can I continue breastfeeding? Like any transition, some of these issues may take time to work through. But, fortunately, where continuing to provide your baby with breast milk is concerned, breast pumps offer working mothers the flexibility to maintain their milk supply and continue nursing, which helps you stay connected to your baby even when you're away. Find out what your state laws say about support of breastfeeding women in the workplace. Many states have laws supporting working breastfeeding women.
A 2007 survey of working mothers conducted by HealthyWomen and Medela about breastfeeding in the workplace found:
Here are some tips to help ensure success for your goal to continue breastfeeding when you return to work:
What You'll Need
It's important to continue breastfeeding for as long as you can and ideally until your baby is one year old and beyond.
Using a Breast Pump
Breast pumps are designed to help:
If possible, you should pump every three hours that you are away from your baby. Make sure to clean the breast pump parts between uses.
Both hand and battery-operated pumps are available. Electric pumps simulate your baby's sucking more effectively and are faster than hand pumps. Many pumps come with discreet carrying cases. The cost ranges from about $35 to $350. Be sure to research which brands and models provide the best performance, reliability and comfort. Also take into consideration the demands of your daily schedule. Many hospitals and clinics rent breast pumps, so you may want to ask your health care provider or a lactation counselor about these and which models would best fit your needs.

Colostrum is rich in nutrients and provides protection against infectious diseases. Because colostrum is so nutrient rich, a very small amount is an entire feeding, so new mothers should not doubt that they can supply their babies' needs.
How do I know if my baby has latched on properly?
If your baby has latched on correctly, he/she should have your entire nipple and most of the areola (the dark skin around your nipple) well into his/her mouth. Make sure your baby's whole body is turned toward your breast, not just his/her head. Try positioning a pillow just below your breasts to ensure the baby is resting comfortably at the same level as your nipple. Your baby's suckling should be even, and you will hear his/her swallows.
Should breastfeeding be painful?
No. Although you may experience some discomfort and tenderness during the first few days, breastfeeding shouldn't be painful. You may feel the slightest tug or pressure sensation. If breastfeeding hurts or you have flu-like symptoms (fever, chills, feeling run down), contact your health care provider.
What is a lactation consultant?
Lactation consultants are professionals who are trained to help mothers who want to breastfeed their babies. Most hospitals and clinics have lactation consultants on staff to help new moms learn how to nurse. They can provide encouragement and assist moms and babies with latching difficulties, painful nursing and other issues that may interfere with efforts to breastfeed. To find a lactation consultant near you, visit http://www.llli.org.
What is the let-down reflex?
You may experience a tingling or tightening sensation (some women describe it as a pins and needles sensation) as your milk lets down and fills your breasts. This reflex means your milk is ready to flow. This sometimes occurs in response to your baby's cry or when a feeding is overdue.
How can I maintain my milk supply?
Your milk supply will respond to your baby's needs—the more your baby suckles, the more milk will be produced. If you're concerned about your milk production, increase the number of feedings a day. Other steps to take include:
• Pumping when you return to work or plan to be away from your baby for an extended period of time
• Getting plenty of rest
• Eating a nutritious diet with plenty of calcium
• Delaying introducing formula or solid foods until six months of age at the earliest
Are there foods or medications that I should discontinue while breastfeeding?
Pay attention to foods that might bother your baby. If you notice a pattern, avoid the food for a few days and then reintroduce it to see what happens. Most mothers who eat a balanced diet and don't have a history of allergies won't need to restrict the foods they eat, except for a few things. Caffeine and alcohol can get into your milk, so limit their intake. You should also avoid certain kinds of fish and shellfish high in mercury; these include shark, swordfish, king mackerel and tilefish. You can safely eat up to 12 ounces (two servings) a week of fish and shellfish low in mercury, including shrimp, canned light tuna, salmon, pollock, clams, haddock, trout and catfish. Some medications may be harmful to your baby if they pass into your milk. Be sure to check with your health care provider about which foods, beverages and medications are safe for you and your baby.
Can I continue breastfeeding when I return to work?
Yes. A growing number of new moms are returning to work and can continue breastfeeding thanks to breast pumps and storage containers, as well as policies that encourage workplaces to be supportive of nursing. Pumping can help you maintain your breast milk supply and keep you connected to your baby, even when you are away. Employers benefit because breastfeeding moms often need less time off for sick babies.
How long can I use stored milk?
The following are some guidelines for freshly expressed breast milk storage from the FDA and the CDC:
• At room temperature (66–72°F) for up to 10 hours
• At 72–79°F for four to six hours
• At 86–100°F for up to four hours
• In a refrigerator (32–39°F) for up to eight days
• In a freezer contained within a refrigerator for up to two weeks
• In a self-contained freezer unit for three to four months
• In a deep-freezer (0°F) for six to 12 months
What are the most recent guidelines for pregnant and breastfeeding mothers about eating seafood?
Some fish contain high levels of mercury that can harm your baby's developing nervous system if eaten regularly. However, a recent federally funded report released by the Institute of Medicine (IOM) showed that the heart benefits of seafood outweigh the risks. The report showed that omega-3 fatty acids found in fish promote healthy vision and brain development in infants whose mothers consume seafood while they are pregnant or nursing.
So does this mean you should eat fish or not? The answer is you should eat fish, but you should make sure it's the right kind. Guidelines issued jointly by the U.S. Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) note that pregnant women can safely eat up to 12 ounces (about two servings) a week of a variety of cooked fish and shellfish with lower levels of mercury, such as shrimp, clams, oysters, salmon, catfish, crab, haddock and trout. If you choose tuna, stay away from albacore, or white tuna, which contains higher levels of mercury than canned tuna. The FDA and EPA also recommend that women of childbearing age, pregnant women and breastfeeding women not eat shark, swordfish, king mackerel or tilefish, which have high levels of mercury.
In addition, they recommend that you check local advisories about the safety of fish caught by family and friends in your local lakes, rivers and coastal areas at www.epa.gov/waterscience/fish. If no advice is available, eat up to six ounces (one average serving) per week of fish you catch from local waters, but don't consume any other fish during that week. And as always, talk with your health care professional about the risks of eating fish and shellfish while breastfeeding. For more information, visit the FDA's food safety website at www.cfsan.fda.gov/seafood1.html.
[Section: Lifestyle Tips]
Lifestyle Tips
Similar to when you were pregnant, it's important that you lead a healthy lifestyle. Make the right choices for you and your baby:
Problems are common during the beginning stages of nursing. Although it's a natural process, breastfeeding is also an art. Take your time and try not to get discouraged or overly stressed, which may make it worse.
Ask for help if you need it. Lactation consultants can offer encouragement and help you overcome difficulties. You may also want to find out about new mom support groups. Talk openly with your partner and family about how they can be supportive of your efforts to breastfeed.
[Section: Health Benefits]
Health Benefits
Health Benefits for Mom and Baby
There are compelling reasons to breastfeed—and both you and your baby benefit.
For Your Baby...
For You...
Breastfeeding saves time and money. There are no bottles to sterilize or formula to mix or warm. In fact, families save an estimated $1,000 to $2,000 on formula per year. In addition, mothers who breastfeed pay fewer out-of-pocket health care costs and take fewer sick days because breast-fed babies are healthier and tend not to need as many visits to their pediatric provider.
[Section: How Milk is Produced]
How the Breast Produces Milk
Milk production is a normal physiologic response to the childbearing experience. New studies shed light on milk delivery, the composition of milk and the anatomy of the lactating breast. This information can help new moms better understand their bodies and how they respond to breastfeeding.
After pregnancy, your breasts produce colostrum—a thick, yellowish fluid—that helps your newborn's digestive system grow and function. Colostrum, often called "first milk" or "immune milk," is rich in nutrients and infection fighting antibodies. While you may wonder whether you're producing enough colostrum or milk for your baby in these first few days, keep in mind your baby's stomach is only the size of a marble. Your mature milk supply typically "comes in" within five days of giving birth.
When you put your baby to your breast, your milk doesn't automatically start to flow. Your body responds to your baby's suckling patterns, which occur in two phases.
Anatomy of the Lactating Breast
New research using ultrasound imaging reveals a number of key differences from the previously held understanding of the anatomy of the breast. These findings can help mothers understand how their infants obtain milk and provide insights for physicians and women considering breast augmentation or reduction surgery.
Key findings include:
The absence of lactiferous sinuses changes our understanding of the way in which the breast produces and delivers milk. For example, it's thought that the lack of lactiferous sinuses is a reason why little milk is able to be expressed prior to milk ejection. Much more study needs to be done to further understand milk delivery.
The number of milk ducts also has implications for breast augmentation surgeons, since the loss of only a few ducts could seriously compromise a woman's ability to breastfeed. The overlapping of fat and glandular tissue also suggests that it is very difficult to remove only fatty tissue from the breast. For more information about the anatomy of the breast, visit www.medela.com.
[Section: Challenges & Support]
Challenges & Support
Overcoming Breastfeeding Challenges
Breastfeeding is a natural and rewarding process; however, many women have trouble during the early stages of nursing. The good news is that most of these problems can be resolved with patience, practice or treatment.
Don't be discouraged if you experience sore nipples, engorged breasts, mastitis or thrush. The severity of these symptoms can vary, but they all are treatable and often avoidable.
Breastfeeding shouldn't hurt. Contact your health care professional if your breasts remain tender or sore, or if you have flu-like symptoms that may indicate an infection. In most cases, you can continue breastfeeding. Emptying your breasts frequently by breastfeeding or pumping can often reduce inflammation and relieve the problem.
Finding Extra Support
Your health care professional may suggest that you work with a lactation consultant (also called a lactation counselor) who can review breastfeeding techniques and help you address any problems that you may have while nursing. Many hospitals and health centers have lactation consultants on staff, so make sure to ask your obstetric or pediatric provider if you think you need extra support. New mother support groups and encouragement from your partner, family, friends and employer are also important.
When Not to Breastfeed
Despite the clear benefits of breastfeeding, there are circumstances when breastfeeding is not in the best interest of the baby. A woman should not breastfeed if her infant is diagnosed with galactosemia (a rare metabolic disorder) or if she has certain health conditions that can be passed to her baby through breast milk, including:
Mothers who use illicit drugs, drink excessive amounts of alcohol or are taking prescribed chemotherapy or radiation therapies for cancer also should not breastfeed. If you have a herpes lesion (sore) on your breast, you should not breastfeed.
Women who have had breast reduction surgery or breast implants may not be able to breastfeed because of the impact these surgeries can have on milk production. However, each woman's breast anatomy and breast surgery is unique, so in many instances it is possible for a woman who has had this type of surgery to breastfeed. Discuss any concerns you may have about your ability to breastfeed or complications you may experience breastfeeding with a lactation consultant.
[Section: Tips for Success]
10 Hints for Ensuring Success
Start early. Learn as much as you can about breastfeeding before your baby is born so you'll feel prepared. Try to breastfeed your baby soon after giving birth (within the first hour). Newborns sleep a lot, so you may have to wake him/her every couple of hours for a feeding. Ask to keep your baby in your hospital room (called "rooming in"). Mother-infant rooming in is becoming more accepted as hospitals try to support early breastfeeding.
Review nursing techniques with a lactation consultant or nurse. Learn how to position your baby to properly latch on to your breast. This will improve your confidence when you return home.
Nurse frequently (8–12 times in 24 hours) and anytime your baby seems hungry. Your milk supply responds to your baby's demand—the more the baby suckles, the more milk will be produced. Many health care providers recommend breastfeeding on demand rather than according to a predetermined schedule. Watch for early signs of hunger, which include:
• Increased alertness or activityBe aware that crying is a late sign of hunger. Try to feed your baby before he/she becomes overly hungry and starts to cry. Offer both breasts during feedings. Usually breastfeeding takes 10 to 20 minutes for each breast. However, from time to time your baby may become full after feeding on just one breast. If this is the case, remember to pump the breast that remains full to avoid engorgement or discomfort. Your baby will empty the first breast it nurses at more completely than the second breast, so make sure that you alternate which breast you begin nursing with at each feeding.
Know how much milk is enough. Many nursing mothers worry about whether their baby is getting enough nourishment. An easy way to gauge whether your baby is getting enough milk is to pay attention to the number of wet, dirty diapers (six to eight wet diapers and three to four yellow, seedy bowel movements by day five are good signs). Keep in mind that it's normal for babies to lose some weight (about 7 to 10 percent of birth weight) within the first week. If you are still concerned about whether your baby is getting enough milk, seek the advice of a health care professional or lactation consultant. Also keep in mind that babies are born with a special supply of fat (called brown fat) that only newborns have. This fat is meant to sustain the baby until its mother's milk comes in. Between this fat supply and your colostrum, baby has no need for supplemental feedings.
Choose a comfortable position. Breastfeeding is very personal. There are a number of ways to hold your baby while breastfeeding. See what feels most comfortable for you and your baby. (See the American Academy of Family Physicians Web site for more information.)
• Cradle position: Place your baby's head in the crook of your arm. Support his/her back and bottom with your arm and hand.No matter which feeding position you use, make sure your baby's whole body is turned toward your breast, not just his/her head. Your baby should have your entire nipple and most of the areola (dark skin around the nipple) well into his/her mouth.
Breastfeeding shouldn't hurt. If you feel pain or discomfort, your baby is probably not latched on properly. Gently place your finger into your baby's mouth to break the suction and try again. You may want to position a pillow just below your breasts or under your arm to support yourself and ensure the baby is at the same level as your nipple. Contact your health care professional if the pain continues or if you notice flu-like symptoms.
Take care of yourself. Get plenty of rest and eat well-balanced meals to regain energy. A good rule of thumb to make sure you are taking in enough fluid is to have something to drink each time you nurse.
Ask about medications. Talk with your health care providers about any prescription medications or over-the-counter drugs or herbs you are taking just in case these may be harmful to your baby.
Refrain from giving your baby other liquids or formula during his/her first six months.
Delay introducing bottle nipples or pacifiers to let your baby develop a good sucking pattern and become familiar with feeding from your breast. If you plan to return to work, try introducing a bottle filled with your breast milk during week three to six (depending on how soon you plan to go back), after breastfeeding is well established.
[Section: Tips for Working Moms]
Returning to Work: Breastfeeding Tips for Working Moms
The transition back to work after maternity leave can be emotional. You're probably asking yourself lots of questions: Can I overcome the guilt of leaving my baby? Will I be able to juggle motherhood and work? How can I continue breastfeeding? Like any transition, some of these issues may take time to work through. But, fortunately, where continuing to provide your baby with breast milk is concerned, breast pumps offer working mothers the flexibility to maintain their milk supply and continue nursing, which helps you stay connected to your baby even when you're away. Find out what your state laws say about support of breastfeeding women in the workplace. Many states have laws supporting working breastfeeding women.
A 2007 survey of working mothers conducted by HealthyWomen and Medela about breastfeeding in the workplace found:
Here are some tips to help ensure success for your goal to continue breastfeeding when you return to work:
What You'll Need
It's important to continue breastfeeding for as long as you can and ideally until your baby is one year old and beyond.
[Section: Using a Breast Pump]
Using a Breast Pump
Breast pumps are designed to help:
If possible, you should pump every three hours that you are away from your baby. Make sure to clean the breast pump parts between uses.
Both hand and battery-operated pumps are available. Electric pumps simulate your baby's sucking more effectively and are faster than hand pumps. Many pumps come with discreet carrying cases. The cost ranges from about $35 to $350. Be sure to research which brands and models provide the best performance, reliability and comfort. Also take into consideration the demands of your daily schedule. Many hospitals and clinics rent breast pumps, so you may want to ask your health care provider or a lactation counselor about these and which models would best fit your needs.
