The NUK Perfect Match teats are ideal for your baby, thanks to their adaptive design. The teat of the bottle is uniquely soft and flexible, just like a mother's skin, allowing it to gently conform to your baby's lips and palate. The smoothly conical shape facilitates proper intake: with the mouth open and the lips wrapping around the teat. The innovative Anti-Colic valve helps prevent harmful air swallowing, with 3 size options for the teat that regulate milk flow in the best way for your baby.
