The Dr. Brown’s baby bottle features a patented internal vent system for vacuum-free feeding. Known as positive-pressure flow it allows babies to feed at their own pace and is more similar to breastfeeding. As the baby feeds, air is channeled from the nipple collar (not the silicone nipple) through the vent system, to the back of the bottle. Air bypasses the breast milk or formula which means no oxidation of nutrients which helps to preserve levels of nutrients like vitamins C, A and E. Plus by eliminating the vacuum and air bubbles, this bottle helps to reduce feeding problems like colic, burping and gas.
