This is the plush lamb companion that generates soothing sleep-inducing sounds while infants lie on him, available only from Hammacher Schlemmer. A sound module hidden in the billowy, pillow-like head plays one of four sounds at the touch of a button: a mother’s heartbeat as heard within the womb, a gentle rain shower, the ocean surf, or a harmonic whale song. Parents can adjust the volume and length of time each sound plays (23 or 45 minutes). The mat unfurls to provide portable comfort for a sleepy infant at grandma’s or just a cozy place for tummy time at home. The thickly padded bed is made of non-toxic and hypoallergenic polyester that can be spot-cleaned. Non-slip backing keeps the mat securely in place. Includes two AA batteries. Newborns and up. 43" L x 29" W x 9 3/4" H. (4 1/2 lbs.)
