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