Hatch vs Dohm. Two sound machines, one nursery, and a tired parent trying to figure out which one makes bedtime less of a hostage negotiation. I have good news and slightly weird news. The good news: there’s a pretty clear answer. The weird news: in our house, the answer was “both.” That sounds like I lost an argument with a baby registry. I didn’t. (This time.) They just do completely different jobs.
Here’s the lineup. Our Yogasleep Dohm Classic sits in the hallway outside our son’s door, soaking up the noise from the rest of the house. Our Hatch Rest+ 2nd Gen lives inside his room, where it’s mostly a dim overnight night light and the nap-time alarm clock, using light and sounds to wake him up. It can do white noise too. We just keep that at a very low volume, and only when we need it.
The short version: Get the Dohm if you mainly want simple, steady background sound. Get a Hatch if you’ll actually use the light and wake-up features. Get both only if you have both problems. Two machines is our setup. It is not a requirement for raising a human.
One plot twist before we dive in: Hatch doesn’t sell our Rest+ anymore. Buy a Hatch today and the one you bring home is the Hatch Baby, which I haven’t used. So everything I say about the Hatch Baby comes from Hatch’s own product and support pages, not from my hallway. Research, not a review.

The Dohm: Our Hallway Bouncer
Bedtime doesn’t shut the house down. People still walk around. People still talk. Somebody runs the dishwasher, and somebody opens the one cabinet with a squeak that sounds engineered by NASA. And every one of those noises gets three times louder the second a toddler falls asleep. That’s not science. That’s just the rules.
That’s where the Dohm earns its keep. It sits in the hallway outside his door and pumps out a steady whoosh, so the random spikes from the rest of the house don’t stand out as much. It doesn’t soundproof anything. It’s less a wall and more a crowd. The squeaky cabinet doesn’t disappear. It just gets lost in the noise.
The beauty of the Dohm is that it’s gloriously dumb. In the best way. There’s a real fan motor inside, two speed settings, and a cap and collar you twist to change the volume and the tone. No apps. No charging. No screen. Yogasleep is very proud of that, and honestly, so am I. It looks like a little white UFO, or a hockey puck that went to finishing school. Plug it in, twist until it sounds right, walk away. That’s the whole manual.
Parking it in the hallway also keeps the main sound source out of the bedroom and farther from his ears. That’s a big reason I like this layout, and I wrote a whole post on the hallway setup if you want the long version.
The tradeoff: it makes one sound. That’s it. No night light, no lullabies, no wake-up cue, no battery. If any of those are on your list, the Dohm isn’t going to sprout them. It’s a fan in a nice hat.
The Hatch: The Night-Shift Supervisor Inside the Room
Plot twist number two: our Hatch isn’t really a second sound machine. It’s mostly a light.
Overnight, the Rest+ glows as a dim night light, which is all you want for a 2 a.m. check when you’d prefer not to step on a dump truck in the dark. (You’ll step on the dump truck anyway. At least now you’ll see it coming.) At nap time, its light and sounds handle the wake-up, which beats me opening the door and announcing “NAP’S OVER, BUDDY” like a game-show host. When we do want white noise in the room, it stays down at a whisper.
So the split is simple. The Dohm handles the noise out there. The Hatch handles the light and the routine in here. Neither one is moonlighting as the other from a different outlet.
Which brings us to the real Hatch question: will you actually use the light and routine features? If yes, getting light and sound in one device is genuinely handy. If you already have a night light you like and just want steady fan noise, you’re paying extra for features that sit there looking cute.
And a word of warning, parent to parent: a wake-up light is a tool, not a contract. A toddler can see the light change and still open negotiations.
Heads Up: Hatch Doesn’t Make Our Rest+ Anymore
Bad news if you were hoping to just copy our setup: Hatch’s own support site says it no longer manufactures or sells the Rest+ 2nd Gen, and it points shoppers to the Hatch Baby instead. (The regular Rest 2nd Gen is gone too.) If you already own one, nothing changes. Ours is still clocking in every night.
Here’s the part I’ll genuinely miss: the battery. The Rest+ has battery backup, and it has saved us during power outages. That matters, because we get a lot of them. When the power drops, the Rest+ just keeps going, which is exactly the moment you don’t want the nursery changing on a sleeping kid. A room that suddenly goes dark and silent is not the kind of surprise anyone wants at 3 a.m.
The Hatch Baby doesn’t have that. Hatch says it needs to stay plugged in and has no battery backup. And to be fair, the Dohm doesn’t have a battery either, so in an outage both of today’s options go quiet. If outages are a regular thing where you live too, Hatch itself points battery-seekers to its portable Go model. Worth a look as a backup.
Hatch Baby: What You’d Actually Be Buying Today
Quick reminder: I haven’t used the Hatch Baby, so this section is homework, not a review. Here’s what Hatch’s own pages say, and what I’d check before clicking buy.
- It needs the app and Wi-Fi to set up. Hatch’s setup instructions have you download the Hatch Sleep app, and they say Wi-Fi is required. After that, there’s a big button on top that starts your favorite sound-and-light combo and a knob for volume. The Dohm, by comparison, needs an outlet and a wrist.
- No battery. Already covered, but it’s the biggest difference from our Rest+, so it gets its own bullet. It earned it.
- The subscription is optional. According to Hatch’s membership page, sleep sounds, solid and dynamic lights and manual schedules are included free. Hatch+ adds stories and music, sleep consultants, sleep guides and smart nap reminders. The Hatch Baby comes with three months included, and the membership page lists Hatch+ at $6.99.
My take: start with the free stuff and see if it covers you. Pay for the bigger library only if you’ll actually use it, not because a toddler-shaped guilt cloud floated over the checkout page. That cloud does not help with the credit card bill. And if bedtime stories are the real draw, I broke down the two big screen-free story speakers in Toniebox vs. Yoto.
And read the full model name before you buy, anywhere. “Hatch sound machine” is a product family, not a spec sheet. A glowing review of an older Rest doesn’t automatically describe the thing in your cart.
Dohm vs Hatch: Which One Do You Actually Need?
Choose the Dohm if sound is the whole job
Want steady fan noise, real buttons and zero setup? The Dohm Classic is the easy call, especially if your lighting situation is already sorted. You give up variety and smart features. If you didn’t want those anyway, that’s not a sacrifice. That’s a feature.
Choose a Hatch if light and wake-up cues matter too
Our Hatch earns its outlet with the night light and nap wake-ups, not the white noise. If that sounds like how you’d use it, the Hatch Baby is the one Hatch sells now. Just go in with your eyes open: it needs Wi-Fi and the app for setup, and there’s no battery backup.
Use both only if you have two separate jobs
We run both because we want background sound outside the room and light inside it. That’s the whole secret. There’s no magic sleep formula hiding in owning two devices. If the room is already quiet and you mostly need a dim light, you might not need a dedicated sound machine at all. I dig into that in do you actually need a baby sound machine, and if you want options beyond these two brands, my best baby sound machine guide covers the rest of the field.
The One Volume Note I’ll Make
No lecture, but this one matters. The American Academy of Pediatrics’ guidance on noise and kids notes that some infant sleep machines can produce hazardous noise levels. Its advice is simple: “If you use a sleep machine, place it as far away from the baby’s head as possible and use it for a short time only.”
So keep the volume low, keep the machine away from the crib, and resist the urge to keep cranking it up to out-shout a loud house. You will not win that arms race. That’s part of why our main noise machine lives in the hallway, and why the Hatch inside the room stays down at a whisper. Also, keep cords away from little hands, and keep any hallway machine out of the walking path, unless you enjoy 2 a.m. surprise yoga.
Hatch vs Dohm FAQ
Is Hatch better than Dohm?
Neither one is better. They’re built for different jobs. The Dohm Classic is a simple fan-based sound machine. A Hatch adds a night light, scheduled light-and-sound routines and app control. We use both because we need both jobs done. Asking which is better is a bit like asking whether a fan beats a lamp.
Can you put a Dohm outside a bedroom door?
Yes. That’s exactly where ours lives. It masks household noise from the hallway. It doesn’t block sound, though, so how well it works depends on your layout.
Does the Dohm Classic need Wi-Fi or a subscription?
No. It’s a plug-in machine with physical controls. No app, no account, no monthly anything. Just a twist and a whoosh.
Is the Hatch Rest+ discontinued?
Yes. Hatch’s support site says it no longer makes or sells the Rest+ 2nd Gen and recommends the Hatch Baby instead.
Does the Hatch Baby have a battery backup?
No. Hatch says the Hatch Baby has to stay plugged in. For a house like ours that gets a lot of outages, that’s the biggest thing we’d give up moving on from our Rest+.
Do I need two sound machines for a toddler?
Probably not. We have two because the Dohm handles sound outside the door and the Hatch handles light inside the room. Figure out which of those jobs you actually need done before you buy anything. Your outlets will thank you.
The Bottom Line
The real Hatch vs Dohm difference isn’t sound quality. It’s what you want the thing to do. Our Dohm has one simple assignment out in the hallway, and it nails it. Our Hatch keeps a dim light on overnight and runs nap wake-ups inside the room, with quiet white noise when we need it. That split works for us.
If you only need one of those jobs done, buy for that job. There are already enough things plugged in around a toddler, and toddlers treat every one of them like a personal challenge.
