Hatch has spent years refining the sleep aid that lives on countless nursery nightstands. The Rest 2nd Gen takes the original formula and makes it smarter, pairing colored light and sound into routines that signal bedtime without requiring you to be in the room. This is a device built for the long haul, from newborn bassinet to big-kid bed.

The core trick is the time-based light and audio automations. You set a “wind down” color and sound, then a separate “sleep” color that stays on all night, then a “wake up” cue. Over weeks, the toddler learns that the orange glow means quiet time and the green light means morning. The sound library is solid—white noise, lullabies, nature sounds—and the speaker is clear enough for stories at higher volumes. It runs on corded power, so you never swap batteries at 2 AM.

The biggest limitation is the app. It works reliably for setting schedules, but the touch controls on the device itself are a little finicky if you’re half-asleep. You’ll want to set everything up from your phone and then leave it alone. For families who want a single device that grows with the child and replaces a separate nightlight, sound machine, and OK-to-wake clock, this is the one.
