Research-Based Design: Developed with over 60 years of research into baby's natural sucking behavior, these nursing bottles feature an upgraded design. They include a research-based latch-on line to promote appropriate latching and an even softer nipple that closely resembles a mother's breast. Supports Breastfeeding: The SofTouch Baby Bottles are crafted to mimic the feeding movements that babies perform when breastfeeding. This design supports breastfeeding mothers in seamlessly transitioning between breast and bottle feeding. Anti-Colic Design: The bottles are equipped with an advanced air vent system that minimizes swallowed air as the baby drinks. This helps reduce the risk of colic and discomfort for the baby. Specially Designed for Newborns: Suitable for babies from birth (0+ months), the 160ml bottle comes with an SS size nipple specially designed for newborns. The round-cut opening of the nipple allows milk to flow out consistently and gradually, supporting the baby's sucking ability at this early stage when they have yet to develop jaw muscles. Functional and Practical: The bottles are designed to be easy to use and clean, providing parents with peace of mind and convenience during feeding times. Overall, the Pigeon SofTouch Bottle PPSU 160ml Twin Pack offers a combination of research-backed design, functionality, and practicality to support both breastfeeding and bottle-feeding mothers in providing the best possible feeding experience for their newborns.
