NUK

The NUK® Smooth Flow™ Anti-Colic Nipple is the only nipple that adjusts flow based on how your baby drinks, adapting to their suction strength ensuring they will always have the right flow rate. This allows baby to maintain their natural feeding behavior while decreasing stress, frustration, and gas. The advanced 1-piece Anti-Colic Air System helps reduce colic, gas and spit-up. NUK® Smooth Flow™ nipples are 100% silicone, BPA-free and designed to fit all NUK® bottles.
