The anatomical nipple is curved at the top for a natural fit to the baby’s palate with an angled tip for easy tongue placement. The curved top promotes a tongue placement and sucking technique where the sides of the tongue cup around the nipple, as it, does during breastfeeding. The angled tip means that the baby does not need to suck as hard, as with a round nipple, for the pacifier to flatten inside the mouth.
The nipple is equipped with a valve, that lets out air when the baby closes down on the nipple. This ventilation system causes the air from inside the nipple to be pushed out through the valve thereby flattening the nipple to shape naturally after the baby’s oral cavity. The valve is also the reason why water can be present inside the nipple after cleaning and sterilization. If this is the case, simply just squeeze the nipple flat to press out the excess water.
