Breast-Like Design: The teats have a distinctive silicone design that feels closer to the skin and mimics the natural flex and movement of a mother's breast. This feature promotes a comfortable feeding experience for babies and supports the transition from breastfeeding to bottle feeding. Easy Latch-On: 95% of mothers reported that their baby accepted the soft silicone teat with a skin-like feel, making it the most easily accepted and breast-like teat. This encourages a natural latch and facilitates feeding. Anti-Colic: The teats feature an anti-colic valve built into the design, which reduces excessive air flow during feeding. This helps babies ingest more milk and less air, thus preventing symptoms of colic. Different Flow Rates: The Closer to Nature teats are available in various flow rates to accommodate the needs of growing babies. The fast flow teats are recommended for babies aged 6 months and older. BPA-Free: Tommee Tippee ensures that their baby bottle teats are BPA and phthalate-free, providing parents with peace of mind regarding their baby's safety. Compatibility: It's important to note that Closer to Nature teats are only compatible with Closer to Nature bottles. Recommended Replacement: Tommee Tippee recommends changing bottle teats every two months, or immediately if they become damaged or weakened. Overall, the Tommee Tippee Closer to Nature Fast Flow Teats offer a combination of comfort, convenience, and safety, making them an excellent choice for babies transitioning to faster flow rates at 6 months and beyond.
