Enhanced efficiency from a manual breast pump A manual breast pump offers you total control of the suction level & pumping rhythm. The unique Philips AVENT Manual Breast Pump assures you enhanced efficiency, being clinically proven to express more milk than a hospital electric pump. Soft massage cushions trigger natural let-down, like baby. Patented massage cushions flex in & out, replicating baby's suckling action & stimulating a fast, natural let-down.

Is it worth breastfeeding if I'm going back to work soon? The more you can be with your baby for the first 4 months, the better for both of you, as the early weeks at home are when your milk does most good.
