Dr. Brown's award-winning Natural Flow Feeding System sets the standard for colic-free feeding. Now available in an all-glass, BPA-free style, these Dr. Brown's bottles still feature the patented internal vent system that made the original Natural Flow bottle famous.

By allowing air to enter through the nipple collar (without being incorporated into the breast milk or formula), Dr. Brown's baby bottles enable a "Natural Flow" that reduces air bubbles and vacuum. Now Moms can say "goodbye" to colic, spit-up, burping, gas, and everything in-between. The positive-pressure design of Natural Flow bottles also helps reduce fluid build-up in baby's ear!

Ergonomic Natural Flow bottles have an easy-to-read formula level gauge, and nipples are resistant to collapse. Connects directly to breast pumps. No expensive liners to buy! Easy to clean and dishwasher safe.

Made of heavy-duty glass, these all-new Dr. Brown's baby bottles are BPA-free and can be integrated with their silicone nipples and their breast pump.

This Natural Flow bottle #262 set comes with two 7 oz. glass standard baby bottles, two level one silicone nipples, two-piece patented internal vents, one cleaning brush, and instructions.
