WHY WHITE NOISE HELPS BABIES SLEEP

Babies love white noise. They spent 9 months in the womb listening to constant loud sounds, so silence is actually stressful! White noise mimics the environment of the womb, creating a blanket of sound that helps babies fall asleep faster and stay asleep longer.


White noise creates a comfortable sleep environment by blocking outside noises (TV, siblings, doorbell) that usually wake your baby. These soothing sounds act as instant relief for colic, calm crying periods, and activate the calming reflex in newborns.
