The medical grade, silicone nipple is more than 2 inches in diameter at the base and has variable thicknesses so it feels more like the real thing. As your baby sucks, the long nipple adjusts, mimicking the way a human breast reshapes during breastfeeding, promoting correct oral development and healthy teeth. The nipple also features a double venting system, helping reduce colic and promoting healthy digestion.
