Original Mason Bottle

The most natural way to bottle-feed a breastfed baby.

No plastic, no shortcuts, no guessing what's in it. The Original Mason Bottle pairs a real glass mason jar with a wide, breast-like silicone nipple, so babies move between breast and bottle without a fight. A built-in dual-valve FussFree™ ventilation system vents air as baby drinks, cutting down on the swallowed air that leads to gas, spit-up, and colicky nights.

Because it's just a jar, a nipple, and a ring, there's nothing to trap milk residue and nothing that needs a specialty brush. When baby's ready, the same jar becomes a sippy cup, a snack cup, or a storage jar — one purchase, years of use.
