Yogasleep Dohm Classic
A real fan makes natural, non-looping sound with nothing to configure.
- Real fan
- No app
- Non-looping
Short version: the Dohm Classic is the better pure white-noise machine; the Hatch Rest 2nd Gen is worth it if you also want a night light, phone control and a toddler time-to-rise clock.
The Yogasleep Dohm Classic makes sound with a real fan inside: natural, non-looping, adjustable with two speeds and a twist collar, and no app at all. The Hatch Rest 2nd Gen combines multiple sounds, a color night light, a time-to-rise light and an audio monitor, all controllable from your phone, with an optional Hatch+ subscription.

Head to head, the Dohm wins on the sound itself. Because a real fan moves air inside, the sound never loops or repeats, which some parents and babies find more soothing than digital tracks.
There is nothing to set up, update or connect: plug it in, pick one of two speeds, and twist the collar to shape the tone. It keeps working the same way for years.
It does only one thing. There is no night light, no timer and no remote control, so changing it means going into the room.
The Hatch Rest replaces three gadgets: a sound machine, a dimmable night light for feeds and changes, and a time-to-rise light. Being able to change any of them from your phone means you don’t open the door and wake a light sleeper.
Its long-term value shows up in the toddler years, when a scheduled color change teaches when it’s OK to get up.
The tradeoffs: digital sound rather than a real fan, an app and account to manage, and some content locked behind an optional Hatch+ subscription; the core features work without it.
Whichever you choose, how you use it matters more than which one: keep it away from the crib and the volume low.
If yes, the Hatch saves buying one separately. If you already have one, the Dohm covers sound.
The Dohm needs none. The Hatch needs an app for its best features.
A 2014 study in Pediatrics found some infant sleep machines could exceed recommended noise limits at max volume close to the crib. Place either across the room at low volume.
The Hatch adds value as your child grows; the Dohm is a simple machine you may keep for adult use.
For features, yes: night light, app control and time-to-rise. For pure, natural white noise, many prefer the Dohm’s real fan.
No. Hatch+ is optional; the core sound, light and time-to-rise features work without it.
Low, and away from the crib. The Pediatrics study recommends placing machines as far from the infant as possible, at low volume.
It plugs into the wall and is compact enough to pack, though a smaller battery machine is easier for travel.
Many families use a dim, warm light for night feeds. Keep bright light low near sleep times.
We compared Yogasleep’s and Hatch’s published features and the 2014 Pediatrics study on infant sleep machine sound levels, plus AAP safe-sleep guidance.
