商品説明

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.
