My Baby Wakes Every Hour: What's Happening
It's not insomnia or bad luck. It's biology — and it has a solution.
Babies have sleep cycles of 45-50 minutes. At the end of each cycle they have a micro-awakening — open their eyes, look around, and if they don't know how to fall back asleep on their own, they cry. That's not a medical problem. It's a skill they don't yet have: sleep self-regulation. The good news: it can be trained.
A baby sleep cycle
Minute 0-5
Light sleep: dozing off, easily woken by noise or movement.
Minute 5-25
Deep sleep: slow breathing, relaxed muscles, hard to wake.
Minute 25-45
REM (active sleep): moves, makes faces, may vocalize. Looks like dreaming.
Minute 45-50
Micro-awakening: cries if they can't self-regulate. This is where most parents despair.
How to help without creating dependencies
Wait 60-90 seconds before intervening — sometimes they fall back asleep on their own
Put the baby drowsy but awake in the crib (not asleep in your arms)
Continuous white noise (not intermittent) throughout the night
Room temperature: 18-22°C is the optimal range
Check hunger: a hungry baby will never self-regulate
Tracking trick: if you log in mi·ma what time they ate and when they slept, you'll see the pattern in 3 days. You'll know if they wake from real hunger or sleep dependency.

Baby's sleep cycle is 45-50 min. Each awakening at cycle's end is normal — the goal is for them to learn to fall back asleep on their own.
