Meet Dex, Liz & Don

3 furry friends with unique features: their soothing sounds will help your baby to settle more easily.

Dex the dog

This cute little puppy cannot wait to sooth your little one.

Liz the lamb

Soft and furry Liz loves to play her melodies to help babies sleep.

Don the donkey

Heartbeat & White noise

Newborns don’t need silence. After having spent 9 months in the womb where sounds of blood flow and heartbeat can get louder than a vacuum cleaner, babies will calm down and sleep better with sounds familiar from the womb.
