Should I express one breast at a time or both together?
It's very important for mothers who express regularly and infrequently or never breastfeed, to express both breasts at the same time. It helps maintain their milk supply. Double expressing sends a stronger signal to the brain to create the let-down, emptying the breasts more effectively. This provides more milk and ensures ongoing production. It also increases the amount of fat in the milk, which is especially important for small premature babies. Double expressing also saves a lot of time, more than two hours a day for some mothers. It can be done with a double electric pump; two single electric pumps; one single electric pump and a hand or constant-suction pump; or one single pump and manual expression. Double manual expression uses one hand on each breast and a large bowl to catch the milk.
