Soothe your baby to rest with Kids Line's Calming Center. The two side ramps help keep baby centered on the pad while the vibrating motors within help calm your restless baby. Noise activated speakers also located within the ramps play calming sounds, including heart beat, when baby cries. The heat stamped pattern on the top surface of the pad provides that extra warmth and comfort to help create a tranquil area. Buttons on the remote glow in the dark, making it easy to find and use in a dark room. Requires 4 AA batteries and comes with a zipper pocket to hold the battery pack. Calming Center measures 38?L x 27.5"W.
