The Sweet dreams lamb music box is true to its name. The music box makes sure baby dreams sweet dreams and gently cradles baby to sleep. The music box plays the German lullaby "Weisst Du, wieviel Sternlein stehen" (Do you know how many stars there are shining in the sky?) and lasts about 1 1/2 minutes. The music box is removable. The music box makes a wonderful gift idea for newborn babies.
