Ask a breastfeeding mom what her favorite essential is, and it's bound to be the Haakaa pump. It works as a manual pump or milk collector and can be used while you're nursing your baby.

How? Simply suction the Haakaa to the breast you aren't nursing your baby on, and the pump will use negative pressure suction to pull from your letdown and catch milk while you're nursing.

Not only is the Haakaa great for building up a freezer stash, it can also help with that initial letdown leak.

*The Generation 1 Haakaa silicone pump holds up to 4 oz. of breastmilk. Price shown for one Haakaa pump.
