Dr. Brown's Polypropylene Newborn Feeding Kit

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.

Designed to:

• 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

Feeding Kit Includes:

• Three 8-oz Standard bottles, two 4-oz bottles, plus two extra Level-Two nipples and two Storage/Travel caps
• Patented two-piece internal vents, travel disks, caps, cleaning brush, and instructions
