Most parents discover very quickly the calming effect that white noise can have on a crying baby. The Gro Company has put that knowledge to good use in the past couple of years with a few products that are almost guaranteed to soothe your child. The latest is the very cute – but equally useful – Ollie the Owl. The cuddly sleep aid is, as the name suggests, a bit of a night owl that will lull your child to sleep with the choice of a lullaby, a soothing heartbeat, rainfall and so on. It has a built-in night-light in the centre. So far, nothing too extraordinary. But Ollie also has what Gro calls CrySensor technology, which will activate if there's a sudden noise, or even a sharp movement. Then Ollie kicks in with white noise to soothe your baby back to sleep.
