CozySleep: Baby White Noise

About this app

Give your baby the gift of deep, restful sleep — every night. CozySleep plays scientifically proven white noise, pink noise, and brown noise to soothe newborns, calm colic, and create the perfect sleep environment for your infant or toddler. Trusted by parents for nap time, bedtime, and those 3 AM moments. WHY WHITE NOISE WORKS Babies spend 9 months surrounded by sounds louder than a vacuum cleaner. The quiet of a bedroom is actually unfamiliar — steady, gentle sound is what feels safe and womb-like. Research shows continuous background noise reduces the startle reflex, masks household interruptions, and helps babies stay in deeper sleep cycles longer. CozySleep delivers high-quality, seamlessly looping audio so the sound never cuts out, never restarts, and never wakes your baby.
