Curve appeal! Meet Nursh Curve, a new baby bottle nipple for the Nursh bottles you already love. Designed to help babies easily switch between breastfeeding and bottle-feeding, Nursh Curve has a design that features a gradual transition from nipple to base, promoting a deeper latch as babies drink from their baby bottles. The Nursh Curve also features a latch line indicator that helps you ensure your baby gets proper positioning every time while the textured top helps baby feel their way into that perfect latch. It's an easy way to help your little one as they feed, and together they make feeding less stressful for both you and your nursing baby. With four flow rates to choose from (Preemie, slow flow, medium flow, fast flow), Nursh Curve also adapts to your little one's needs as they grow. Made from 100% platinum food-safe silicone, Nursh Curve breastfeeding bottle nipples provides a soft, familiar feel to baby and an easy-to-clean design for you that can be boiled, sterilized or tossed into your favorite dishwasher basket.
