Invented by a doctor, and effectively used in hospital nurseries for over 25 years! The Original Slumber Bear contains the ONLY actual intra-uterine, recorded womb sound to help lull your Baby to sleep in minutes! Each Original Slumber Bear also arrives with its own Silkie! Parents can bond with Baby by keeping Silkie close to their skin, transferring their scent to the blanket. The Slumber Bear sound and motion sensors re-activate recording when Baby cries or jostles bear. Additional hook and loop straps allow you to secure the removable audio box to crib rails, strollers and more!
