Dr. Brown’s bottle includes a patented two-piece internal vent system that works unlike some other bottle design. The vent system fully vents our bottle for vacuum-free feeding, which we call positive-pressure float, very similar to breastfeeding. As the baby feeds, air is channeled from the nipple collar in the course of the vent system, bypassing the breastmilk or formula, to the back of the bottle.
