The Moonie Humming Teddy Bear and Humming Bunny soothe and put children to sleep with safe pink noises recorded in a natural environment.
The sounds are real recordings of natural pink noise, not computer-generated noise.
Thanks to the fact that the sound of the heartbeat is a real recording from inside the mother's belly, the baby can calm down and feel safe with the already familiar sound. The sound of sea waves was recorded on the Baltic Sea, and the sounds of a forest stream, help mute sounds from everyday surroundings, so that everyday household noises do not wake the baby from sleep.
