When babies start kicking, grasping, lifting their heads or sucking on a soother, it is all an important part of their daily “fitness regime”, because the muscles in their legs, arms, backs and even in their faces too, have to develop and be exercised. The interplay between an agile tongue, powerful jaw muscles and a correctly-shaped roof of the mouth is an important requirement for healthy, trouble-free breathing, problem-free feeding and, later, speech development. The NUK Baby Rose & Blue Soothers have the NUK shape that is right for the jaw. The anatomically-shaped mouth shield fits your child´s face perfectly. The soother is available in two styles. The teat  is made of silicone, a synthetic material that is completely free from harmful substances and has a pleasantly smooth surface. This material is very soft, particularly heat-resistant and neutral in taste. Silicone is less flexible than latex and a silicone NUK Soother should be replaced once the first signs of use appear (e.g. scratches, bite marks or small holes).
