- 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 breastmilk or formula.
- The air is then channeled through the internal vent system to the area above the breastmilk 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.
