Tommee Tippee super soft silicone, easy latch-on teats with patented ripple design have been designed with breastfeeding experts to mimic the natural flex, stretch and movement of a mum's breast. Made from super soft, resilient silicone, these baby bottle teats have a matt texture that feels closer to skin for complete comfort at feeding time. These baby bottle teats feature an easi-vent valve that reduces excessive air flow, so little ones ingest more milk and less air, preventing symptoms of colic. Together with the bottle's sensitive valve, the wide bottle neck encourages your baby's intuitive feeding action. Designed to be held in the most natural position during feeding, the compact shape of the bottle also allows baby to be closer to you.
