The "NUK" silicone nipple imitates a mother's nipple at the time of breastfeeding, so it is optimally shaped for the baby's mouth. The special air valve Nuk Air System equalizes the pressure in the bottle and reduces the risk of colic caused by harmful swallowing of air. The middle hole of the nipple is for milk. Orthodontic teat "NUK" provides the process of feeding as close to natural as possible, and also contributes to the correct formation of the bite and the maxillofacial apparatus as a whole.
