How do Dr. Browns bottles actually work? I think they’re supposed to reduce air intake but how do they do that?
In: 1
This is from the Dr Brown website: That one small straw is actually the reservoir of a powerful internal vent system that’s clinically proven to reduce colic, decreases spit-up, burping, and gas. The internal vent system works by channeling air away from the liquid contents in the bottle, be that milk or formula, eliminating negative pressure and air bubbles. No air in the milk means no air in baby’s belly – and less feeding problems.
