The ONLY pacifier that INSTANTLY closes when it drops, keeping fewer germs out of baby's mouth. Thanks to an ingenious design, if this soother is dropped, the protective cover automatically closes around the nipple IMMEDIATELY! No more worrying about giving your child back their pacifier after its fallen on the floor. The protective Shields are attached to the pacifier so there are no more lost soother covers either. Silicon teat (nipple) and perfect from birth.
