Breastfeeding in the Workplace
It is entirely possible -- and recommended -- to continue breastfeeding after returning to work. You can pump your milk and store it for your baby’s caretaker to feed when you are away. Many employers will provide a clean, private place for you to pump during the work day. In fact, it is the law in most states.
If you have difficulty pumping enough milk to store, you should talk to a lactation consultant. S/he may be able to help you get your supply up. Another option is to supplement with formula. You can breastfeed when you are with your baby, and formula can be used when you are not. You should still pump your breasts during the work day to relieve the pressure and to maintain your milk supply. The more you pump or nurse, the more milk your body will produce.
If possible, wait a minimum of two to three weeks before giving your baby a bottle. Since it is easier for a baby to get milk from a bottle than from your breast, she may develop a preference for the bottle. Your milk supply will decrease if you do not feed or pump often. Allowing at least two to three weeks helps establish your milk supply. In the beginning, your body makes as much milk as it can. After a few months, milk is produced based on demand.
The longer you are able to breastfeed your baby, the better. But also remember that any length of time is beneficial to your baby.
