Babies can benefit from the soothing sounds of a white noise machine from birth! After all, white noise (shushing) is an integral part of Dr. Harvey Karp’s renowned 5 S's for soothing babies. That is because white noise mimics the familiar and calming sounds Baby heard on a 24/7 loop in the womb, triggering their innate calming reflex—nature’s “on switch” for soothing and sleep and “off switch” for fussing. To get started with white noise, play SNOObear sounds during your baby’s relaxing bedtime routine—and then keep the sounds going even after you have given goodnight kisses. Integrating white noise into your baby’s night-night routine conditions your nugget to associate white noise with sleep. That means, as Baby grows, they will hear white noise and think, “it must be time to go to bed!”
