The Neno Baby Bottles are designed for infant feeding, suitable from birth up to 3 months. These bottles feature a BPA-free construction, ensuring the safety and health of your baby. The anti-colic system helps reduce air intake, minimizing discomfort and fussiness during and after feeding. The silicone teat is soft and natural-feeling, promoting an easy transition between breast and bottle, and is specifically designed for babies aged 0-3 months.
