Soothers can comfort your baby during the day and at sleep time. With the DAY & NIGHT set, you have a dedicated soother for both moments at hand. Both are gentle on skin. The NIGHT soother has a glow-in-the-dark knob that allows you and baby to find it in the dark. Without a ring, your baby’s sleep is not disturbed when moving at night.Cleaning:Clean the pacifier before every use with warm water. Do not use abrasive cleaning agents. Excessive use of detergents may cause plastic components to crack. Should this occur, replace your pacifier immediately. All commonly used forms of sanitizing are suitable for cleaning pacifiers. Before touching pacifiers, ensure all surfaces are clean and wash your hands thoroughly.
