White noise vs. natural sounds: which works better?

Every parent has heard about white noise. But is it really the best sound for sleep? The answer: it depends on age.

White Noise (0-6 months)

White noise mimics the sounds in the womb (blood flow, digestion). A newborn spent 9 months listening to constant noise at around 80dB. Total silence is stressful for them.

Recommendation: White noise at 50-60dB (the volume of a normal conversation), continuously throughout the night, at least 2 meters from the crib.

Brown Noise (3-12 months)

Lower, deeper than white noise. It sounds like strong wind or a waterfall. Warmer and less harsh — ideal for babies who have grown used to white noise and need something different.

Natural sounds (6+ months)

Rain: The most popular natural sound. The random but constant rhythm relaxes the adult brain — and works the same way for babies.

Ocean: Waves have a roughly 8-second rhythm that syncs with sleep breathing. Ideal for restless babies.

Forest: Crickets plus wind through leaves. Best for daytime naps — it's not intense enough for nighttime.
