Tommee Tippee Advanced Anti-Colic Medium Flow Teats For 3 Months+ Babies is distinctive, silicone, breast-like teat feels closer to skin and flexes like mum for a comfortable feed and supports in the transition from breastfeeding to bottle feeding. The most easily accepted and breast-like teat, ever, to encourage a natural latch. It can be used together with Advanced Anti-Colic baby bottles to help combat colic while ensuring a comfortable feeding experience for you and your baby. These bottles are easy to clean either in a sterilizer, by hand or in the top rack of the dishwasher. Always BPA and phthalate-free for your ultimate reassurance. Every baby is different but as a guide we suggest slow flow for 0+months, medium flow for 3+ months and fast flow for 6+ months. Advanced Anti-Colic teats are only compatible with Advanced Anti-Colic bottles.
