Dr. Brown's baby bottles are fully-vented and clinically proven to reduce colic.* Dr. Brown's anti-colic internal vent system helps prevent ingestion of air bubbles and eliminates the vacuum effect which helps reduce spit-up, burping and gas. It also means no nipple collapse or fluid buildup in baby's ear.
* Ellett, Examination of the Effect of Dr. Brown’s Natural Flow Baby Bottles on Infant Colic, Gastroenterology Nursing, May/June 2006
A 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 preserve levels of important nutrients -- vitamins C, A, and E + lipids. The vent system reduces air bubble oxidation of the milk, which is fragile and susceptible to nutrient loss.
Chosen by lactation consultants and recommended by pediatricians,** Dr. Brown's slow-flow rate is ideal for switching between breast and bottle. The internal vent system and silicone nipple work seamlessly together, resulting in controlled flow so babies feed at their own
