White noise: Magic for babies to big kids…and beyond! Before they're born, babies bask in the low rumbly sounds of the womb. These sounds keep them happy and calm…and that's why our little ones continue to love white noise after they arrive. The right white noise—like SNOObie's Rain on the Roof soundtrack—helps turn on a baby's calming reflex—their natural “on switch” for sleep. Using SNOObie's sounds in a bedtime routine helps little kids figure out that white noise means sleepytime. Plus, white noise helps to distract from common sleep-interrupters (think: teething or sniffles) and covers over the sounds of dogs barking or car alarms that might yank them from their dreams.
