Even though it feels like magic, there is science behind my Hummy. These unique toys emit 5 types of sound including white noise & amniotic fluid with heartbeat, which has been shown to improve babies’ sleep. In case of newborns a recent study suggested the likelihood of a baby falling asleep is increased threefold in response to white noise. All functions can also be controlled using the free my Hummy app, which works using super safe low energy Bluetooth.
