The new NUK Space Silicone Pacifier: for particularly sensitive baby skin. The  NUK Pacifier  impresses  with  its  particularly  flat  and  thin  baglet,  which  offers  sufficient space for the natural sucking movement. The NUK Space Pacifier, therefore, fits optimally into the mouth when the baby sucks on it. More than 95% of babies accept the NUK Pacifier*. The NUK Space Pacifier also has particularly extra-large ventilation holes that ensure maximum air circulation  and  allow  the  baby's  delicate  skin  to  breathe.
