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. Helping you Parent On Set contains: 3x 5oz and 3x 9oz bottles with slow flow nipples, 4x medium flow nipples, 2x spare valves, 2x small nipple cleaning brushes 80% of the 210 parents we consulted who tried this bottle agreed that it successfully reduced colic symptoms (June 2017)
