First Impression

by Holly feat. Cora (2m)

"Leon is so soft and beautifully sleepy! Even with the hummy heart inside, he isn’t overly bulky. I was so surprised that Cora settled with it after just 10 minutes."


The Verdict

by Holly feat. Cora (2m)

"We love Leon! He’s worked wonders to help Cora settle, drift off and even sleep longer. It’s such a useful thing for sleep-deprived parents!"

The KIDLY view

"Life in the womb isn't a quiet one. Babies settle really well once they are earth side with this clever gadget that lets them settle to sleep with the familiar humming of white noise."

The full story

Leon With Sleep Sensor Heart is a cuddly bear with a humming heart. Designed to help babies and their parents get a better nights sleep, this innovative piece of baby tech plays white and pink noise, helping little ones to drift off and encouraging their shut eye to last longer. With 5 different sounds which can be set to play at 16 different volumes, you are able to experiment to find the perfect match for your baby. Maybe they are fans of lapping ocean waves or it's the constant tapping of the heartbeat which they prefer. Once bed time comes around, either set it to play for 60 minutes and then fade out, or for those who like constant background noise, the non-stop system lets it play for a solid 12 hours. Leon's a buddy that will listen out for your little night owl as much as you, if he hears any background noice, he'll automatically turn up, with the goal of settling them back off to sleep. Thanks Leon.
