The Playtex® VentAire® Advanced Bottle System's revolutionary venting feature is designed to prevent air from mixing with the liquid, and getting into your baby's tummy. And, the angled bottle promotes the semi upright feeding position recommended by pediatricians to help prevent ear infections.

For anybody curious they do work. I bought my son which he's 4 months old and these are amazing. No more sucking in air which means no more Belly Aches..... Be sure to check out my video..it about a mean lil Chihuahua .... /watch?v=m461_k5kZcc
