The Dr. Brown’s newborn bottle features a patented two-piece internal vent system that works unlike any other bottle design. The vent system fully vents the bottle for vacuum-free feeding, which goes by the name, positive-pressure flow, similar to breast feeding. As the baby feeds, air is channelled from the teat collar through the vent system, bypassing the breast milk or formula, to the back of the bottle. Air never mixes with the breast milk or formula which minimises oxidation and helps maintain essential nutrients like vitamins C, A and E.

Babies feed more comfortably because the vent system allows them to nurse without fighting the negative effects of a vacuum or the discomfort of ingesting air bubbles. This helps to reduce feeding problems like colic, burping, and wind. The breast milk or formula flows freely, without teat collapse. No vacuum, no bubbles, no teat Collapse!
