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. SOUNDS YOUR BABY WILL LOVE • Classic White Noise — the universal soother, perfect for newborns • Brown Noise — deeper, richer tone; especially calming for fussy babies • Pink Noise — balanced frequencies shown to improve sleep depth • Fan & Air Conditioner — familiar household hum for instant calm • Shhhh Sound — mimics the sounds babies hear in the womb • Heartbeat & Womb Sound — recreates the comfort of the womb • Rain & Thunderstorm — rhythmic nature sounds for deep sleep • Ocean Waves — slow, rolling waves for peaceful nap time • River & Forest — immersive nature soundscapes • Hairdryer & Vacuum — surprisingly effective household soothers • Washing Machine — gentle rumble that babies find deeply calming • Soft Lullabies — gentle melodies for a calm, peaceful bedtime FEATURES BUILT FOR EXHAUSTED PARENTS • Seamless looping — no gaps, no startles, no wake-ups • Background play — works while screen is off • Timer with fade-out — dims sound slowly so you can sneak out quietly • Offline mode — works without Wi-Fi, even on flights • Favorites — save your baby's go-to sounds for 3 AM access • Safe volume reminders — protect your baby's hearing • Dark mode — no blinding screen during night feeds HOW TO USE 1.
