You are 34 weeks pregnant, you cannot sleep, and the neighbor upstairs sounds like they are moving furniture at 2am. Or you are building a registry and want one device that will carry you from the third trimester through the toddler years. Either way, you are probably looking at the Hatch Rest+ and the Yogasleep Dohm, the two devices that dominate nearly every nursery sound machine conversation in 2026. They do similar jobs in fundamentally different ways. The Hatch is a connected device โ smart home adjacent, app-dependent, feature-rich. The Dohm is a 60-year-old design that uses a real spinning fan to generate noise the same way a box fan in a window does, except tuned for sleep. This comparison covers sound quality, price, ease of use, travel, longevity, and โ critically โ which one actually helps a pregnant woman sleep better at 3am. Our pregnancy sleep aids guide covers additional options if you want a broader view.

Option A: Hatch Rest+ 2nd Gen
The Hatch Rest+ is what happens when a sound machine gets a full smart-home upgrade. At $89โ$129, it does the work of three separate devices: a sound machine, a dimmable night light (in any color), and eventually a toddler clock that shows kids when it is okay to get out of bed. You control everything from your phone via the Hatch app โ set schedules, pick sounds, adjust brightness, program the "time to rise" color cue โ without getting out of bed or entering the nursery.
The sound library is extensive: white noise, pink noise, brown noise, rain, ocean, lullabies, and more. Sound quality from the digital speaker is good โ cleaner highs than the Dohm and better for music-style sounds. The 2nd-generation model added a rechargeable battery, which was the main complaint about the original, making it genuinely useful for travel during the third trimester or hospital stays. With 28,000-plus reviews averaging 4.7 stars, it is one of the most-reviewed baby sleep products in any category.
- App-controlled sound, light, and time-to-rise
- Color-changing night light with dimmer
- Library of sounds including white, pink, brown noise
Hatch Rest+ Pros
- All-in-one: sound, night light, and toddler sleep trainer in one device
- App control without getting out of bed during night feeds
- Portable rechargeable battery โ works in the hospital or hotel
- Extensive sound library with white, pink, and brown noise options
- Grows with your child from newborn through age five or six
- 4.7-star rating with 28,000+ reviews
Hatch Rest+ Cons
- Higher price ($89โ$129) vs. the Dohm
- App dependency for full functionality โ setup requires a smartphone
- Digital sounds have a slightly processed quality vs. mechanical white noise
- Premium feature tier may require subscription (check current pricing)
Option B: Yogasleep Dohm Classic
The Yogasleep Dohm has been making the same fundamental sound since 1962, when it was sold as the "Sleep Mate." Inside the dome is a real fan motor. Rotating the outer shell adjusts airflow through vents, changing the tone. Flipping between two speed settings changes volume. That is the entire interface. No app, no wi-fi, no software updates. Just mechanical white noise.
At $49โ$69, it costs less than the Hatch and has accumulated 55,000-plus reviews averaging 4.6 stars โ one of the most reviewed sound machines of any kind. Sleep specialists often prefer the Dohm's mechanical noise over digital alternatives because true broadband fan noise masks a wider frequency range than most digital recordings. For covering a snoring partner during pregnancy or masking traffic noise, the Dohm's low-frequency content gives it a physical advantage. It is not glamorous, but it is extremely effective.
- Natural white noise from real fan motor
- Two-speed dome with adjustable tone and volume
- No loops, no digital recordings
Yogasleep Dohm Pros
- Real fan motor โ true mechanical white noise with no loops
- Simple two-speed, adjustable-tone interface requires no tech skills
- $49โ$69 โ significantly cheaper than the Hatch
- 55,000+ reviews, 4.6-star average โ battle-tested over decades
- No app, no subscription, no wi-fi dependency
- Exceptionally durable โ many units last 10โ15 years
Yogasleep Dohm Cons
- Wall outlet only โ no battery or portable mode
- No night light, no sleep training features
- Volume and tone limited to physical vent adjustment โ less precise
- Single sound type only โ no pink noise, brown noise, or music
Sound Quality: Mechanical vs Digital
This is the most important technical difference and one most buyers overlook. The Dohm's real fan generates what engineers call "broadband white noise" โ sound spread evenly across all frequencies from the lowest bass rumbles to high-pitched treble. This broad coverage is what makes it excellent for masking a wide variety of ambient noises. The Hatch plays digital audio files, which sound good but have a narrower effective masking range, particularly in the sub-200 Hz bass range where traffic and HVAC rumble live.
For most nursery situations โ covering a sleeping baby from household sounds โ both work equally well. If you live in a noisy urban environment with heavy traffic or an adjacent HVAC unit, the Dohm's mechanical broadband noise has a genuine edge. If you want a variety of sound types โ ocean waves for yourself, soft lullabies at naptime, white noise for overnight โ the Hatch wins on versatility.
Using Sound Machines During Pregnancy
Sound machines are not only for newborns. Many pregnant women use them in their own bedroom from the second trimester onward to help manage pregnancy insomnia, mask a snoring partner, and reduce light-sleep micro-arousals that disrupt the sleep they do get. Both the Hatch and the Dohm work well for adult bedroom use. Place either device on a nightstand or dresser, set it to a moderate volume (around 50 dB โ similar to a shower), and it meaningfully reduces how often ambient noise wakes you up.
The Hatch has the advantage for dual bedroom-nursery use because you can control it from your phone without walking across the house at 3am. The Dohm has the advantage for adults-only bedroom use because its mechanical sound tends to be more immediately relaxing for most adults who grew up sleeping with a fan. See our third-trimester insomnia tips for more strategies that pair well with either device.
Price and Long-Term Value
The Dohm at $49โ$69 is straightforward value โ a device that will likely outlast your child's infancy and continue working in a bedroom or office for a decade. The Hatch at $89โ$129 has a higher upfront cost but a longer functional lifespan as a parenting tool: newborn white noise, toddler night light, and eventually a visual sleep trainer for a 2- to 5-year-old. Spread over three years of nursery use, the Hatch's cost-per-month is around $3โ$4, roughly the same as the Dohm. The question is whether you want those extra features or prefer maximum simplicity.
Travel Considerations
The third trimester often brings hospital bag packing, babymoon travel, or grandparent visits โ all situations where a portable sound machine matters. The Hatch Rest+ 2nd Gen's rechargeable battery runs for several hours and makes it genuinely pack-friendly. The Dohm requires a wall outlet and is not suitable for hotel rooms without one near the bed (most do have one, but positioning matters). If travel is a priority before or after birth, the Hatch is the obvious choice.
Our Verdict โ Who Should Pick Which
Choose the Hatch Rest+ if: you want one device from the nursery through the toddler years, you appreciate app control for middle-of-the-night adjustments, you need portability for hospital or travel, or you want a night light bundled in. The Hatch is the better long-term investment for parents who will use it actively for three or more years.
Choose the Yogasleep Dohm if: you want the best pure white noise at the best price, you prefer zero-tech simplicity, you plan to use it primarily in your own bedroom for pregnancy sleep or as a set-it-and-forget-it nursery device. The Dohm is the better choice when features are not what you are paying for.
Better Option for Your Specific Situation
Persona 1: 36 Weeks Pregnant, Urban Apartment, Cannot Sleep Through Traffic
You are in a noisy city, your windows let everything in, and sleep is already fractured. Get the Dohm. Its mechanical broadband noise covers low-frequency urban sound better than digital alternatives, it runs all night without battery concerns, and you do not need an app at 2am. Keep it on the nightstand and move it to the nursery after birth.
Persona 2: Building a Nursery, Want One Device for Years
You want the same device to serve as sound machine, night light, and eventually a toddler sleep trainer so your 3-year-old knows when to stay in bed. The Hatch Rest+ is purpose-built for this. Its growing feature set becomes more useful as your child gets older, and the app control is genuinely helpful during exhausted newborn nights.
Persona 3: Planning a Hospital Delivery and Postpartum Hotel Stay
You want something to block hospital hallway noise during labor and recovery, then work at your parents\' house when you visit with the newborn. The Hatch Rest+\'s rechargeable battery makes this possible. Toss it in your hospital bag with a phone charger and it does double duty from day one.
