Reduces colic, spit-up, burping & gas. The patented vent system eliminates air and vacuum to allow baby to feed comfortably and reduce many common feeding problems.

New research. A recent university study set out to measure nutrient levels in baby bottle breastmilk and formula. It was determined that Dr. Brown's fully-vented bottles help maintain levels of important nutrients. The Dr. Brown's vent system reduces air bubble oxidation of the milk, which is very fragile and susceptible to nutrient loss. Health tip: Vitamins C, A and E, and lipids, or good fats, are all naturally occurring in mom's breastmilk and are critical for health and growth in infancy. Patented internal vent system. 1. Air enters the blue collar and routes directly through the internal vent system. 2. The air channels through the vent tube, bypassing the milk, to the end of the bottle. 3. The vent prevents aeration of the milk, vacuum pressure, and nipple collapse. 4. Baby feeds comfortably while the milk flows freely, like breastfeeding.
