Overview A soother or dummy is a useful aid to help relax your baby. The asymmetrical shape featured on all NUK Soothers is designed to adapt to baby s mouth perfectly allowing an optimal interplay between the lips, palate, jaw and tongue. Nurturing these muscles will assist in healthy oral development later in life including trouble-free breathing, problem-free feeding, and, later, speech development. Most importantly, a soother can help satisfy an infant s natural need to suck. The NUK Air System allows air to escape through the valve allowing it to stay soft and flexible, keeping its shape and allowing a satisfying sucking action. NUK Silicone Soothers are made from high-quality, synthetic material. The clear, silicone material is easy to clean and particularly heat-resistant. It can be boiled, is free from harmful substances, odourless, transparent and has a smooth surface all qualities that are important in a soother. NUK is the only brand with teats and soothers accredited by the Oral Dental Health Foundation.
