Dr. Brown's Natural Flow Standard Starter Kit

The patented Natural Flow internal vent system is the only vent that eliminates the vacuum and the air bubbles found in most baby bottles. It allows air to enter through the nipple collar without being incorporated into the breast milk or formula.
The air is then channeled though the internal vent system to the area above the breast milk or formula. Babies feed more comfortably because the vent allows them to nurse without fighting the negative effects of a vacuum or the discomfort of ingesting air bubbles. This helps to reduce colic, spit-up, burping and gas.
The breast milk or formula flows freely through the nipples as the air is channeled to the top of the bottle. This positive pressure eliminates nipple collapse, and can help reduce build up of fluid in baby's ear.
Unique internal vent eliminates the vacuum and air bubbles to help reduce colic, spit-up, burping and gas
By eliminating the negative pressure, it can help reduce build up of fluid in baby's ear
