Most bedtime battles get treated as a discipline problem. A large share of them are a timing problem. A child asked to fall asleep before their body is ready will lie in the dark and call out; a child kept up long past the point where sleep was easy will fight the pillow instead. From the doorway, those two look identical, and neither is fixed by being firmer.
This article is about the hour itself rather than the steps of the routine: how much sleep a child of three, six or ten actually needs, what time that puts bedtime at, how to move a bedtime that is wrong, and what to check when the hour is right and your child still will not settle. If the sequence of your evening is the part that needs work, start with our guide to building a bedtime routine and come back to the clock afterwards.
Why will my child not fall asleep at the bedtime I have set?
Because two separate systems have to agree, and only one of them answers to a parent. Sleep pressure builds steadily from the moment a child wakes up, while an internal body clock opens and closes a window during which falling asleep is easy. Bedtime works when it lands inside that window with enough pressure built up behind it.
Set bedtime too early and you have the classic scene: a child who is not tired, in a dark room, with nothing to do but call for water. Set it too late and you get the opposite failure, an overtired child who is wired rather than sleepy, because the easy window has already closed. Parents often read both as defiance. Neither is.
The practical consequence is that there is no single correct bedtime, and copying a friend's schedule rarely works. The right hour is a calculation from two numbers you already have: the time your child has to be awake, and the amount of sleep a child their age needs.
How much sleep does my child actually need?
Between 10 and 13 hours per 24 hours for a child aged 3 to 5, and between 9 and 12 hours for a child aged 6 to 12. Those figures come from the American Academy of Sleep Medicine's child sleep duration health advisory, which counts naps towards the total for the younger group.
These are not arbitrary numbers. The consensus recommendations were endorsed by the American Academy of Pediatrics, and regularly sleeping within the recommended range is associated with better attention, behaviour, learning, memory and emotional regulation. Regularly sleeping less is associated with the reverse.
Two caveats matter more than the headline. The ranges are wide on purpose, because individual need varies by a couple of hours; a nine year old who thrives on nine and a half hours is not doing anything wrong. And the total is per 24 hours, so a four year old who still takes a 90 minute nap does not need those 90 minutes again at night.
What time should bedtime actually be?
Take the time your child must be awake, subtract the sleep they need, then subtract another 20 to 30 minutes for the time it takes to fall asleep. That is your target lights-out. For most families the wake time is fixed by school, which makes bedtime the only variable you control.
Here is the same calculation for three common wake times, before subtracting falling-asleep time:
| If your child has to be awake at | Age 3 to 5 (10 to 13 h) | Age 6 to 12 (9 to 12 h) |
|---|---|---|
| 6:30 | 17:30 to 20:30 | 18:30 to 21:30 |
| 7:00 | 18:00 to 21:00 | 19:00 to 22:00 |
| 7:30 | 18:30 to 21:30 | 19:30 to 22:30 |
Read the ranges as boundaries rather than as a menu. If your current bedtime sits outside the range for your child's age, that is worth fixing before anything else. If it sits inside the range and evenings are still hard, the hour is probably not your problem, and the sections below are.
How do I move a bedtime that is at the wrong hour?
Move it in small steps and anchor the morning first. The technique sleep clinicians use is called bedtime fading: start by putting the child to bed at the time they currently fall asleep, so that falling asleep is quick, then bring bedtime forward by about 15 minutes every few nights until you reach the target.
It sounds counterintuitive to start by making bedtime later, and that is the point. The child stops associating the bed with lying awake, which is the habit that keeps the fight going. In a 2018 open trial of a parent group education approach, bedtime fading in preschool children cut the average time to fall asleep from roughly 23 minutes to 13, reduced night waking and reduced bedtime tantrums, with the gains still present at follow-up.
Behavioural approaches to bedtime problems have an unusually solid evidence base for parenting advice. The review conducted for the American Academy of Sleep Medicine by Jodi Mindell and colleagues, covering 52 studies of behavioural treatment of bedtime problems and night wakings, found that 94 percent of the studies reported efficacy, with more than 80 percent of treated children improving and holding the improvement for three to six months.
Two things make fading work in practice. Keep the wake time fixed, including at weekends, because a variable morning moves the whole clock. And expect the first three or four nights to be worse before they are better, since you are trading a familiar routine for an unfamiliar one.
What if my child gets out of bed once the lights are off?
Give the getting up a shape instead of trying to eliminate it. The best studied version is the bedtime pass: the child gets one card at lights-out, exchangeable for a single trip out of the room or one parental visit, and once it is spent the parent stops responding to further calls.
In a randomised controlled trial of 19 children aged 3 to 6 with bedtime resistance, published in the Journal of Pediatric Psychology, children in the bedtime pass condition left their rooms, called out and cried significantly less than controls, settled faster each night, and kept the improvement at three months. Parents rated it as acceptable and easy to run, which matters more than it sounds: the intervention a tired adult can actually keep up at 21:00 is the one that works.
The pass works because it gives the child a legitimate, limited version of the thing they wanted, which removes the incentive to escalate. It also gives the parent one clear decision to make instead of twenty.
What else keeps a child awake when the hour is right?
Light, stimulation and fear, in roughly that order of frequency. Evening light exposure and stimulating content push the internal clock later, which is why the last hour before bed matters more than the two hours before that. Naps that run too late do the same by bleeding off sleep pressure.
Fear is the one parents most often misread as stalling. A child who suddenly needs the door open, the hall light on and three checks is usually not negotiating; something has changed. We wrote a full plan for that in why a child suddenly becomes scared of the dark. Separation is the other common cause, and it has its own approach, which we set out in getting a child to sleep in their own bed.
An honest limit: sleep advice is written for typical development, and it does not cover everything. Persistent loud snoring, long pauses in breathing, extreme difficulty falling asleep every night for months, or daytime sleepiness that does not fit the hours slept are reasons to speak to a doctor rather than to adjust the schedule again.
What does the last half hour look like when the timing is right?
Quiet, repetitive, and the same every night. Once the hour matches the child's sleep need, the job of the routine is simply to make the transition predictable: dim light, no screens, one story, one goodnight, in the same order. Predictability is doing the work here, not novelty.
Some families use a story as that final fixed step, and on the nights when an adult cannot sit down for it, an audio story keeps the shape of the routine without adding a screen. That is the role Ted plays for some households: an interactive plush that tells and co-writes stories aloud, with the parent setting the language, the topics, the tone and the limits from the app, no camera, and a single purchase at 129 euros with no subscription. It is an addition to the routine rather than a replacement for the adult, and no talking toy has been shown to make a child fall asleep faster. If bedtime is going badly, the hour on the clock is still the first thing to check.
Frequently asked questions
What is a good bedtime for a 5 year old?
For a five year old who has to be awake at 7:00 and no longer naps, lights-out between 19:00 and 20:00 lands inside the recommended 10 to 13 hours. If they still nap in the afternoon, a later bedtime is normal and expected.
Is it bad to put a child to bed too early?
It is not harmful, but it usually backfires. A child put down well before their body is ready spends the extra time awake in bed, which teaches them that bed is a place for lying awake and makes settling harder over time.
How long should it take a child to fall asleep?
Roughly 15 to 30 minutes is typical. Falling asleep in under five minutes most nights can be a sign of not enough sleep overall; taking more than 45 minutes most nights suggests bedtime is too early or the wind-down is too stimulating.
Should weekend bedtimes be the same as school nights?
Keeping the wake time steady matters more than the bedtime. A lie-in of an hour or so is fine; a two hour shift each weekend moves the body clock later and makes Monday night hard.
My child says they are not tired. Are they lying?
Usually not. Overtired children genuinely do not feel sleepy, because the window in which sleep comes easily has closed. That is an argument for an earlier bedtime rather than for a later one, introduced gradually.
