For nearly 40 years, the original slumberBEAR with SILKIE® blanket has been helping newborns transition from womb to the world in hospital nurseries and homes worldwide. It is the ORIGINAL audio pacifier with an actual recording made inside a mother's womb. Comforting womb sounds lull Baby to sleep in minutes, or calm them when they are fussy. Sound/motion sensors re-activate recording when Baby cries or the bear is moved. Additional straps allow removable sound box to attach to crib rails, strollers, and more.
