Early morning waking
Five in the morning, every day, ready to play. The fix is counter-intuitive: in most cases you need an earlier bedtime.
Five in the morning. Not five and a grumble that goes back to sleep: five and a wide-awake child, babbling, pulling themselves up, ready to start the day.
It is probably the most demoralising sleep problem, because you cannot fix it in the moment. You are not going to get them back to sleep. You are simply going to live the day two hours down.
And the fix is the opposite of what everyone advises.
Why it plays out at the end of the night
Deep sleep is concentrated in the first few hours. At 10 p.m. your child is in the most solid part of their sleep. At 4 a.m. they have almost none left: they drift between light and REM sleep, with barely any accumulated sleep pressure.
That is the most fragile stretch of the whole night. The smallest thing — a shaft of light, a noise from the street, a full nappy, a bladder — is enough to bring them out for good.
So it is not the 5 a.m. waking you need to look at. It is everything that came before it.

Lever number one: an earlier bedtime
I know, it makes no sense the first time you read it.
A child put to bed too late falls asleep in sleep debt. To keep going, their body has released cortisol — an alert hormone. Cortisol does not vanish at the moment of falling asleep: it keeps circulating and fragments the second half of the night, which is already the most fragile.
Result: put to bed at 9 p.m., they wake at 5. Put to bed at 7.45 p.m., they wake at 6.30.
Test it over a full week, not two evenings. Thirty minutes earlier, hold it for seven days, then look. It is the change with the best effort-to-result ratio — and the one nobody thinks of.
The four other levers, in order
Complete darkness. Not dim. In summer it is light by 5 a.m. across much of Europe, and light is the most powerful signal the biological clock has. A decent blackout blind alone often shifts waking by thirty to forty-five minutes.
Continuous white noise. Early-morning sounds — neighbours, bin lorries, birds — arrive exactly when sleep is at its lightest. A constant background masks them. Continuous all night, not just at bedtime: white noise that stops is itself a change of environment.
Daytime sleep. Undersleeping in the day does not lengthen nights, it damages them. Check the naps match their age, and that the last one does not finish too late — a nap running past 3.30 p.m. pushes bedtime back, which takes us straight back to lever one.
How you respond to the waking. If they wake at 5 a.m. and you take them out of the cot, feed them and turn the light on, you have just taught them that 5 a.m. is getting-up time. Wait ten to fifteen minutes before intervening, keep the room dark, stay boring. It does not work the first morning. It works after about ten.
What is not early waking
Before changing everything, check the total.
A child put to bed at 7 p.m. who wakes at 6 has slept eleven hours. That is a full night — they do not have an early-waking problem, they have finished sleeping. In that case the only fix is to shift the whole rhythm later, very gradually, in fifteen-minute steps over several weeks. And sometimes you have to accept that you have a morning child.
When it has nothing to do with rhythm
Early waking alongside loud regular snoring, breathing pauses, mouth breathing or heavy sweating deserves medical advice — sleep-related breathing disorders in children exist and are treatable.
Same if the waking consistently comes with pain crying, an arched back or reflux. No blackout blind fixes reflux.
How long it takes
Allow two to three weeks to see a clear shift, and accept the back-and-forth. The biological clock moves slowly — it is the same mechanism as jet lag, and nobody recovers from a transatlantic flight in one night.
The sign it is working is not waking at 7 a.m. overnight. It is waking at 5.20, then 5.40, then 6.
Frequently asked questions
From what time does it count as early waking?
Before 6 a.m., generally. Waking at 6.15 after an eleven-hour night is not early waking: that child has finished sleeping. The real criterion is the total length of the night, not the number on the clock.
Why does an earlier bedtime make them sleep later?
Because a child who falls asleep in sleep debt produces cortisol, which fragments the end of the night — exactly the stretch where deep sleep has already gone. Going to bed thirty minutes earlier reduces the debt and solidifies the early morning.
Does the room need to be completely dark?
Yes, and it is the cheapest lever. Dawn light is enough to prevent settling back at the end of the night, when sleep is at its lightest. A decent blackout blind often shifts waking by thirty to forty-five minutes.
