There's nothing a parent wants more than for their baby to be comfortable, that's why we've combined our award-winning breast-like nipple with the latest anti-colic innovation to create the Tommee Tippee Advanced Anti-Colic bottle. This is no ordinary baby bottle. It works a little differently from regular bottles to help combat colic, while ensuring a comfortable feeding experience for you and your baby. The unique venting system draws air away from milk, meaning 80% less gas*, and 100% more smiles! Plus, a built-in heat-sensing strip gives extra reassurance that your milk is just the right temperature.
