A 2007 survey of working mothers conducted by the National Women's Health Resource Center and Medela about breastfeeding in the workplace found the top three reasons why working moms decide to continue breastfeeding are: Health benefits for the baby; the emotional bond between mom and baby; and because it is the most natural way to feed a baby.
Plan in advance. Before returning to work, talk with your employer/human resources department about their corporate policies and your needs to continue breastfeeding.
Ask for a private, clean room where you can pump.
Discuss how pumping breaks (20 minutes every 3-4 hours) will fit into your schedule.
Educate your employer about the benefits of breastfeeding (fewer missed work days, shorter absences, etc.).
Buy or rent a breast pump. This will give you the flexibility to maintain your milk supply and also feel connected to your baby even when you're away.
Store your milk safely. You can pump into the same bottles throughout the day as long as the milk is kept chilled.
Seek out other working mothers who can offer you support.
Breastfeed your baby as soon as you get home.
