I’m a big fan of white noise/baby sound machines. (BTW, there’s nothing super special about baby sound machines — they’re basically the same ones that are great for adults.)
But yes, having one can make all the difference in drowning out loud neighbors, cars, sirens… other siblings (ahem). For white noise only, the runaway favorite is the Marpac Dohm ($50). This dual-speed “sound conditioner” has an actual fan inside, which creates the soothing sound of rushing air. Yes, we own 3. Cannot. Live. Without.
The LectroFan ($49) is another crowd favorite. It has a wider range, with 20 non-repeating sound offerings, and multi-level volume control (from whisper to very loud).
The aforementioned Hatch Baby Rest ($59) is a night light/sound machine combo that we love (two birds/one stone…). It’s my top pick FOR SURE.
If you want the pony to do more tricks, check out the Cloud b Tranquil Turtle Sleep Machine ($45), which has natural sounds, lullabies, a rotating projector, and an on/off timer.
Another similar, but cheaper option, is the Summer Infant Slumber Buddies ($24) – check it out here.
Lastly, there are a handful of apps that function as baby sound machines too, if need be; White Noise is an all-around favorite.
