Dr. Brown's Polypropylene Bottle - 8oz.

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

Features:

• Made from BPA free, polypropylene plastic
• Easy to clean and top-rack dishwasher safe
• Connects directly to most breast pumps
• Includes a high-grade Level-One silicone nipple, patented two-piece internal vent, travel disk, cap, cleaning brush, and instructions
