The sound of ocean waves was recorded on the Baltic Sea and the sound of a forest stream in Tarrach. The humming of the Moonie Bears emanates from the surroundings, preventing the baby from being disturbed by everyday household noises. The built-in crying sensor detects when the baby is crying and automatically turns on, so you don’t have to get up to activate it yourself. Moonie comes with an adjustable volume module, allowing you to choose the appropriate volume that meets your child's needs. Moonie also features a soothing lullaby, composed on a kalimba and specifically arranged for newborns.
