You can use the night light with music or light. With three function modes, you can choose to use only music, only light, or both together. Turn on the music, and the Good Night Bear plays classical music and nature sounds for ten minutes. The bear's volume can be adjusted to three levels. The night light features two color options that create a magical atmosphere at bedtime. You can easily attach the cuddly bear to the child's bed. The bear operates on three AA batteries, which are included.
