Tommee Tippee Closer to Nature Fast Flow is a breast-like teat. These distinctive, silicone, easy latch-on, breast-like teats feel closer to the skin and flex like mum's breast for a comfortable feed. 95% of mums reported that their baby accepted the soft silicone teat with a skin-like feel and would recommend it to others. The Closer to Nature teat features an anti-colic valve that reduces excessive air flow, ensuring little ones ingest more milk and less air, preventing symptoms of colic. Tommee Tippee offers different flow rates to keep up with your growing baby. As a guide, the brand suggests slow flow for 0+months, medium flow for 3+ months and fast flow for 6+ months. Closer to Nature teats are only compatible with Closer to Nature bottles. It is recommended to change your bottle teats every two months, and you should change them immediately if they're damaged or weak. Tommee Tippee baby bottle teats are always BPA and phthalate-free. The pack contains two fast flow treats.
