Dr. Brown's Natural Flow 8 oz. Polypropylene Bottles offer moms the benefits of the vent system, but in a polypropylene bottle design. The 8 oz. Polypropylene Bottle uses the same silicone nipples as the Dr. Brown's Standard bottles.
Favored by moms and dads because they reduce feeding problems like colic, spit-up, burping, and gas. The Patented Internal Vent System eliminates air and vacuum to allow baby to feed comfortably. It also reduces air bubble oxidation of the milk to help preserve vitamins and lipids, key nutrients to baby's health.
The fully-vented bottle design provides vacuum-free feeding, like breastfeeding, which can also help reduce build-up of fluid in baby's ear.
|How They Work:|
The Dr. Brown's bottle features a patented two-piece internal vent system that works unlike any other bottle design. The vent system fully vents the bottle for vacuum-free feeding, which they call positive-pressure flow, similar to breastfeeding. As the baby feeds, air is channeled from the nipple collar through the vent system, bypassing the breastmilk or formula, to the back of the bottle. Air never mixes with the breastmilk or formula which minimizes oxidation and helps preserve essential nutrients like vitamins C, A and E.
Babies feed more comfortably because the vent system allows them to nurse without fighting the negative effects of a vacuum or the discomfort of ingesting air bubbles. This helps to reduce feeding problems like colic, spit-up, burping, and gas. The breastmilk or formula flows freely, without nipple collapse.
