The teat has the original NUK shape, which is based on the mother’s breast when breastfeeding. In this way, NUK pacifiers promote healthy oral development, are accepted by 95% of babies** and do not cause nipple confusion.** The teat is so flat, thin and narrow that it fits perfectly in the small mouth and leaves enough space for the tongue and jaw for the natural sucking movement. A fact that midwives, paediatricians and orthodontists** as well as mothers*** confirm. The anatomically correct NUK shape is ideal, because natural sucking has been proven to not only help to take in food, but also helps to develop important skills such as swallowing, chewing and ultimately speaking correctly.
