BPA-Free: The teats are made from BPA-free materials, ensuring the safety of your baby during feeding. Natural Flow: The teats are designed to allow your baby to control the milk flow more naturally, similar to breastfeeding. This helps to reduce overeating and spit-up, promoting a comfortable feeding experience. Anti-colic Valve: The teats feature a responsive valve and a unique skirt system that flexes to allow air into the bottle. This promotes healthy, active feeding and reduces the likelihood of colic, ensuring your baby has a more comfortable feeding experience. Ribbed Teat: The teats have a ribbed texture, providing a secure latch for your baby during feeding, enhancing their feeding experience. The Avent Anti-colic Medium Flow Teats come in a pack of two and are suitable for babies aged 3 months and older. With their unique design and focus on reducing colic, these teats are an excellent choice for supporting your baby's feeding journey.
