The Dr. Brown's Natural Flow baby bottle is the only baby bottle that features a patented internal vent system. This vent eliminates the air bubbles and vacuum effect to allow positive-pressure feeding with no air - similar to breast-feeding.

- Reduce colic, spit-up, burping, and gas
- Prevent air bubbles from forming in milk or formula
- Help reduce fluid in the ear
- Prevent nipple collapse
- Three 8-oz Standard bottles, two 4-oz bottles, plus two extra Level-Two nipples and two Storage/Travel caps
