Klean Kanteen Baby Nipples Slow Flow (2PK)

Kid Kanteen Baby Bottle Nipples are made of medical-grade silicone.?Klean Kanteen enlisted IBLCE-certified lactation consultants in the development of the nipples. Each?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, ensuring proper placement in the mouth, and promoting correct oral development and healthy teeth. The nipple also features a double venting system, which is designed so your baby is swallowing liquid, not air, helping reduce colic and promoting healthy digestion.

These nipples fit 5oz and 9oz Kid Kanteen stainless steel baby bottles. This is pack of 2 slow flow (0-6 months) nipples.
