There?s nothing a parent wants more than for their baby to be comfortable. That?s why Tomme Tippee have combined their award-winning breast-like teat with Anti-Colic technology to create the Tommee Tippee Advanced Anti-Colic bottle. The distinctive three piece Anti-Colic technology draws air away from milk and the star valve keeps milk from traveling up the tube meaning 80 Percent less wind, reflux and discomfort. And 100 Percent more smiles. Plus, a built-in heat sensing straw gives you extra reassurance that your milk is just the right temperature so both you and your baby can feed comfortably.
