Patented internal vent system eliminates the negative pressure and excess air ingestion
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 through 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 and gas.
The Breast milk or formula flows freely through the nipple as the air is channeled to the top of the bottle. Air never mixes with the breast milk or formula which minimizes oxidation and helps maintain essential nutrients like vitamins C, A and E. This positive pressure eliminates nipple collapse and can help reduce build up of fluid in baby's ear.
