No, you do not need one. In the early weeks of breastfeeding it is best to latch the baby to the breast as it helps to build a good milk supply and teaches the baby to breastfeed. If a mother has to return to work or school or has to be separated frequently from her baby an electric breast pump makes this easier. If mom is only away occasionally a manual pump works well and is easier to carry. Whatever ​the situation is, WIC has breast pumps that can meet every mother’s needs. The type of pump will depend on mom’s situation.
