This is the plush lion that generates eight 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 noise of ocean surf, the harmonic sounds of a whale song, Twinkle-Twinkle Little Star, Rock-a-Bye Baby, a classic lullaby, and a tranquil melody. It also has a built-in audio sensor that detects the sounds of a restless child and automatically generates white noise or lullabies for soothing sleep. You can control the volume, and each sound may be set to turn off after 23 or 45 minutes. Attaches to crib, stroller, or car seat with hook-and-loop fasteners. Includes two AA batteries. 9 1/2" H x 6" W x 6" D. (2 lbs.)
