Inspired by mums and designed by experts, our Advanced Anti-Colic Baby Bottle has an extra-wide neck and breast-like teat to help your baby have the most natural bottle-feeding experience with added anti-colic technology to prevent discomfort caused by gas. Tommee Tippee Advanced Anti-Colic baby bottles offer superior performance, our best bottle for reducing colic symptoms†. They work 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 baby, meaning less wind, reflux and discomfort. Topped with our breast-like shaped teat, helping baby get the best latch and reduce air intake. Plus, the venting tube comes with a built-in heat sensing strip that gives you extra reassurance that the milk is a safe temperature for baby. For added peace of mind, the Advanced Anti-Colic baby bottle is completely mess-free and leakproof when the screw ring, teat and cap are all secured (even if it’s turned upside down or shaken). It’s also 100% BPA free so it’s safe for your baby.
