The Lulla Doll from Roro Care imitates closeness by playing a real-life recording of the breathing and heartbeat of a mother at rest and it's soft, natural touch. The aim of the Lulla Doll is to help babies stabilise their own breathing and heartbeat, resulting in longer and better quality sleep as well as added security. When the chest is pressed, Lulla plays a real-life recording of the breathing and heartbeat of a real mother to help reassure and soothe your baby to sleep. Babies prefer to look at something that resembles a human face. The outer is crafted in soft 100% cotton for maximum softness and comfort.
