Dr. Brown's Natural Flow Feeding Bottle, Polypropylene 2-ounce, 2 Pack

Dr. Brown's Standard Bottle is designed using an exclusive 2-piece internal vent mechanism. This facilitates positive pressure flow feeding, which is similar to breastfeeding. During feeds, air is transferred from the teat collar through the vent system to the back of the bottle. The air circumvents the breast milk or formula and minimizes oxidation. Also, the essential nutrients of the feed like vitamins A, C and E are preserved. As babies don't have to fight the discomfort of ingesting air bubbles, feeds are longer and easier. This bottle helps significantly reduce gas, colic and spit-ups.
