To make life easier, you have to understand it first! For more than 60 years, NUK has been listening to the trusted experts; midwives, doctors, nutritionists and especially mothers and fathers, in order to learn about the needs of mother and baby in those precious early years. The NUK orthodontic, asymmetric shape is designed to optimally fit baby?s mouth, encouraging the healthy development of the oral cavity. For this reason, NUK are the ONLY brand to have both teats and soothers approved by the British Dental Health Foundation. NUK First Choice Teats are based on nature, the shape of a mother’s nipple during breastfeeding. This creates a natural drinking action and optimal flow of milk for as natural a feeding experience as possible and makes the transition between breast and bottle feeding easier. The teat also benefits from the NUK Anti-Colic Air System, a special shape and Air System that helps to reduce the chance of baby swallowing air whilst feeding.
