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 breast milk. The Generation 2 Haakaa silicone pump holds up to 5 oz. of breast milk and is designed with a suction base to prevent spilling.

Storing your breastmilk just got easier. The Haakaa silicone milk storage bags are an eco-friendly and convenient way to store and travel with your milk.

Sending your baby off to daycare, or keeping them at home with a nanny? These storage bags hold up to 9 ounces of milk - more than your typical disposable bag - so it's easy for a caregiver to take over on bottle feedings and breast milk handling.

Looking to build up a freezer stash? Fill these bags up and pop them in the deep freeze for future use.

Don't waste that liquid gold - Haakaa storage bags to the rescue.

*Pack of 2, 9 oz. silicone storage bags included.

Earth Mama Organics Booby Tubes work double time - heat these breast packs up to comfort pains, promote a letdown and avoid clogged ducts, or throw them in the freezer for a cold compress on tender, engorged breasts.

Use Booby Tubes when breastfeeding or weaning. Either way, these will have you feeling like a new mom in no time.

*Pack of 2 included.
