It comes with an elegant hidden gathering in an enhanced matte finish for a Premium look. The nipple is round and resembles the shape and size of the mother's breast to provide comfort to your baby. The round nipple and matte lightweight shield are designed to imitate the shape of a mother’s breast and promotes a similar tongue placement and sucking technique when breastfeeding, since the round shape allow the sides of the tongue to elevate and cup around the nipple, just like it does during breastfeeding. The nipple is equipped with a valve, letting 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 lightweight shield is carefully designed to curve away from the sensitive and delicate skin around the baby's mouth, to ensure minimum contact with the baby's nose and mouth, which means less chance of moisture build-up from saliva that can cause rashes and sore spots. The shield comes in one size no matter the nipple size.
