Advanced Anti-Colic Baby Bottle.

Inspired by mum, designed by experts. This is no ordinary bottle. Tommee Tippee Advanced Anti-Colic bottles works a little differently from regular bottles to help combat colic while ensuring a comfortable feeding experience for you and your baby. The unique 3-piece anti-colic venting system draws air away from milk and the star valve keeps milk from traveling up the tube meaning less wind, reflux and discomfort ? 84% of mums who used our anti-colic bottles agreed they reduced their baby?s colic symptoms*. The anti-colic venting tube comes with a built-in heat sensing strip that gives you extra reassurance that the milk is a safe temperature for baby. Dip the tube for 10 seconds to see the milk?s temperature. A pink strip shows that the milk is too hot. Leave to cool down further before feeding your baby. Loved by mums and babies, our easy latch-on, breast-like teat feels closer to skin and mimics the natural flex and movement of a mum?s breast for a comfortable feed. 95% of mums reported that their baby accepted the soft silicone teat with skin-like feel and would recommend to others. The wide neck bottle makes cleaning easy, and the bottles are suitable for use in the dishwasher, microwave and steam sterilisers. 100% BPA-free for complete peace of mind. *Based on 2021 study of 524 parents who use Tommee Tippee bottles, **Made for Mums March 2020.
