By helping babies fall and stay asleep, the Dohm from Marpac is mom and dad's new best friend. Dohm creates the soothing sound of rushing air naturally, without digital loops or recordings. Its unique sound lulls baby to sleep, and its noise-buffering functionality means neighbors outside, parents watching TV, or siblings playing in the next room won't disturb baby. Adjustable tone and volume make it possible to create the perfect sound environment - especially helpful for the nap and bedtime needs of newborns, toddlers, and children. And the Dohm’s compact size makes it portable, too, so your family’s familiar sleep setting comes along - any time, any place. Dohm is the Official Sound Conditioner of the National Sleep Foundation, and this product includes a special pediatric Sleep101 guide from the NSF.
