Dr Brown’s Natural Flow Anti-Colic Options+ Narrow Baby Bottle, Sampler Kit, 1x 4oz/120ml Bottle & 1x 8oz/250ml Bottles with Level 1 Slow Flow Teat, Kit Also Includes 2X Level 2 Medium Flow Teats

Clinically proven to reduce colic, belching and gases by compensating for the negative pressure in the bottle, removing vacuum and air bubbles. They can be used with or without the airing system.

With a US-patented natural flow internal valve system® air removal system, through which when drinking, air is directed from the pacifier through the tube to the back of the bottle, bypassing breast milk or adapted milk. By not allowing them to be mixed, it minimizes oxidation and helps to preserve essential nutrients such as vitamins C, A and E.
