Research-Based Design: Backed by over 60 years of research into baby's natural sucking behavior, the SofTouch nipples feature an upgraded design with a latch-on line for appropriate latching and an even softer nipple that closely resembles a mother's breast. Seamless Breast and Bottle Feeding: The SofTouch Nursing Bottles are designed to mimic the feeding movements babies perform when breastfeeding, supporting breastfeeding mothers to seamlessly switch between breast and bottle feeding. Anti-Colic Design: The teats feature an advanced air vent system that minimizes swallowed air as the baby drinks, helping to reduce the risk of colic and discomfort. Size M Teats: This pack includes two size M teats, suitable for babies aged 3+ months. The Y-cut opening of the nipple allows milk to drip out under pressure, enabling babies to control the flow of milk and further develop their sucking ability, which is particularly important at this age as babies have a stronger jaw muscle. Overall, the Pigeon SofTouch Teat M 2 Pack is designed to promote comfortable and natural feeding experiences for both babies and breastfeeding mothers, while also offering features to help reduce the risk of colic and support babies' oral development.
