By helping babies fall and stay asleep, The Dohmie Serious Sleep Baby Bundle by Marpac is mom and baby"s new best friend. Packed with Marpac"s original tried and true white noise machine, the Dohm-NSF, official sound conditioner of the National Sleep Foundation (NSF), Buddy the Bee Finds His Zs original storybook, and a Sleep 101 brochure from the NSF, restful sleep becomes as simple as the flip of a switch. The Dohm uses electromechanical technology to create the soothing sound of rushing air, without digital loops or recordings, which has been proven to effectively block noises at a broad range of frequencies. The noise-buffering ability 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 soothing sound, especially helpful for the nap and bedtime needs of newborns, toddlers and children. Its compact size makes it easy to throw in the diaper bag for a familiar sleep setting no matter where you are. A consistent sleep-friendly environment is critical in creating healthy, serious sleep patterns for infants, and in providing restful nights for mom and dad too.
