- Our Dr. Brown’s BPA Free bottle features a patented two-piece internal vent
system that works unlike any other bottle design.
- The vent system fully vents our bottle for vacuum-free feeding, which we call
positive-pressure flow, similar to breastfeeding.
- As the baby feeds, air is channeled from the teat collar through the vent system,
bypassing the breastmilk or formula, to the back of the bottle.
- Air never mixes with the breastmilk or formula which minimizes oxidation and
helps maintain essential nutrients like vitamins C, A and E.
