The Tommee Tippee Closer to Nature Baby Bottles are designed to promote natural feeding. Featuring a slow-flow, breast-like teat, these bottles mimic the feel and action of breastfeeding, making the transition between breast and bottle easier for your baby. The integrated anti-colic valve helps to reduce air intake, minimizing discomfort and potential colic. Ideal for newborns and infants, these bottles offer a comfortable and familiar feeding experience, supporting your baby's healthy development.
