Nothing is better for your newborn than a Natural Touch™. The SoftFlex™ Natural Nurser is designed to make breastfeeding and bottle feeding work better together. It features the new Nûby™ Breast Size Nipple which closely mimics the natural shape, feel, and function of a mother’s breast helping to ease the transition from breastfeeding to bottle feeding. Superior anti-colic valves in the base of the nipple help prevent colic, and soft nubs on the surface massage baby’s gums. Additionally, this bottle is made from a high grade of Poly Propelene material which is 100% Bisphenol A FREE and is fully interchangeable with the SoftFlex™ Silicone system.
