Breast-like Design: The teats feature a distinctive, silicone, breast-like design that feels closer to the skin and mimics the natural flex and movement of a mother's breast. This design helps in the transition from breastfeeding to bottle feeding, offering a comfortable feeding experience for your baby. Easy Latch-On: With a design that encourages a natural latch, these teats have been reported by 95% of mothers to be easily accepted by their babies. This feature helps facilitate a smooth transition between breast and bottle feeding. Anti-Colic Valve: Built into the teat is an anti-colic valve that reduces excessive air flow, ensuring that your little one ingests more milk and less air during feeding. This helps prevent the symptoms of colic, providing a more comfortable feeding experience. Different Flow Rates: The Closer to Nature bottle teats are available in various flow rates to accommodate your growing baby's feeding needs. BPA-Free: Like all Tommee Tippee products, these teats are made from BPA-free materials, providing peace of mind for parents regarding their baby's safety. Compatibility: It's important to note that Closer to Nature teats are only compatible with Closer to Nature bottles, ensuring optimal performance and compatibility. Overall, the Tommee Tippee Closer to Nature Medium Flow Teats offer a combination of comfort, convenience, and safety for both babies and parents during feeding time.
