The Infant's Sleep Sound Dolphin.

This is the plush dolphin that generates four different sounds to lull infants to sleep. It re-creates the sound of a mother's heartbeat heard within the womb, a gentle rain shower, the calming sounds of ocean surf, and the harmonic sounds of whale song. You can control the volume, and each sound may be set to turn off after 23 or 45 minutes. The dolphin attaches to a crib, co-sleeper, or bedpost with a hook-and-loop fastener. Child-safe, it is made of non-toxic and hypoallergenic polyester that can be spot-cleaned. Includes two AA batteries. Newborns and up. 10 1/2" L x 6" W x 5" D. (1 lb.)
