Sleep is one of the few parenting problems that gets worse the harder you think about it at 11pm.
If you’ve ever stood outside a bedroom door doing the maths (if they fall asleep now, they’ll get eight and a half hours), you’re in good company. Healthdirect reports that more than one in three children have a sleep problem.
Kids sports and sleep come up constantly on the sideline, usually as a question phrased in hope: if we wear him out, will he finally go down? The honest answer is more interesting than yes. Most of a night’s sleep is decided during the day, but not in the way parents expect. Not in the hour before bed, where most of the advice lives, but in the morning light and the afternoon activity that came ten or twelve hours earlier.
Why is sleep important for kids?
Sleep is when growth happens, when the day’s learning gets filed away, and when the immune system does its housekeeping. None of that is visible, which is part of the problem. What is visible, on a Saturday morning pitch, is everything downstream of it.
A well-slept six-year-old has a go at things. A tired one stands still, gets upset when a drill doesn’t work first time, and wants a parent within arm’s reach. Coaches can usually pick the difference before the warm-up finishes, and it has very little to do with ability.
The importance of sleep for toddlers is bigger again, because so much of the brain and body development that happens between two and five happens during sleep. Toddlers also have the least ability to tell anyone they’re tired. They show it instead, usually as a meltdown over something that wouldn’t have registered the day before.
How much sleep do kids need?
These come from the Australian 24-Hour Movement Guidelines, which set sleep alongside activity and screen time rather than treating it as a separate problem.
Age | Recommended sleep |
0–3 months | 14–17 hours, including naps |
4–11 months | 12–16 hours, including naps |
1–2 years | 11–14 hours, including naps |
3–5 years | 10–13 hours, including naps |
5–13 years | 9–11 hours, uninterrupted |
14–17 years | 8–10 hours, uninterrupted |
So how much sleep does a 7 year old need? Nine to eleven hours, same as every child from five to thirteen. The guidelines overlap at age five, so for a five-year-old anywhere from 9 to 13 hours is within range.
These are guides, not targets to hit exactly. Children vary enormously, and a child who wakes cheerful and copes well with their day is probably getting enough even if the number looks light on paper.
What time should an 8 year old go to bed?
Work backwards from when they have to be up, not forwards from when you’d like the house quiet.
An eight-year-old needs 9 to 11 hours. If school means a 7:00am wake-up, lights out somewhere between 8:00pm and 10:00pm covers the range, and most families land around 7:30pm to 8:30pm once you allow time to actually fall asleep rather than just be in bed.
The more useful point is that the wake time is doing more of the work than the bedtime. Raising Children Network puts it plainly: a regular morning wake time helps a child stick to a regular bedtime. Keep the wake-up steady, including weekends, and the bedtime tends to sort itself out. Let it drift by two hours on a Sunday and Monday night will be a negotiation.
The Sleep Health Foundation suggests bedtime and wake time shouldn’t vary by more than about an hour across the week. That’s the number worth holding onto when school holidays, travel or a season of Sunday games start pulling the routine around.
Signs your child isn’t getting enough
Tiredness in children often looks like the opposite of tiredness. The obvious signals are easy to read. These are the ones parents tend to misread:
- Difficulty settling at bedtime, especially in a child who used to settle easily
- Big evening energy, which reads as being full of beans rather than exhausted
- Small frustrations producing very large reactions
- Trouble concentrating, or reports from school about focus
- Genuinely hard mornings, not reluctance but real difficulty waking
- Falling asleep in the car on short trips
A single bad week means very little. Every family has them. A pattern that runs across a term is worth paying attention to.
What about sleep regression?
Sleep regression is the term parents reach for when a child who was sleeping fine suddenly isn’t. It’s worth knowing it isn’t a clinical diagnosis, and the formal research behind the specific ages people quote is thin. That doesn’t mean the experience isn’t real. It plainly is.
What’s usually happening is that something has changed: a developmental leap, a dropped nap, starting school or daycare, a new sibling, illness, a growth spurt, or a routine that quietly slipped over a holiday period. Most of these settle within a few weeks.
The response is unglamorous and it’s the same response as always. Hold the wake time, get light into the morning, keep the wind-down identical every night, and resist the urge to fix it by pushing bedtime later. Consistency is doing the heavy lifting here, not any particular technique.
Does sport actually help kids sleep?
Australian health services are consistent on this. Children’s Health Queensland advises that daytime exercise and natural light exposure may improve sleep at night, and that children who are inactive during the day, or who don’t get natural light, particularly early in the morning, may find it harder to fall asleep.
The research points the same way but hasn’t fully settled, and it’s worth being straight about where it lands.
A 2025 meta-analysis of 27 randomised controlled trials in children and adolescents aged 6 to 18 found significant improvements in sleep quality, sleep efficiency and sleep duration from exercise interventions. The same review found no change in total sleep time, and the effect on how long children took to fall asleep wasn’t statistically significant. Put plainly: the nights look better, but the trials don’t show children banking extra hours.
Meanwhile a 2024 systematic review in Sports Medicine judged the effect of physical activity interventions on sleep inconclusive, with small effect sizes overall.
So the honest position is this: the advice is well-founded, every Australian health service gives it, the direction of the evidence is favourable, and the size of the effect isn’t nailed down. Anyone telling you that sport will fix your child’s sleep is overselling it, and that includes anyone who runs sports classes for a living.
What’s probably doing the work
Light, especially in the morning. Daylight is the strongest signal a child’s body clock has for working out when the day starts, which is what sets when it ends. Walking part of the way to school is one of the cheapest interventions available. It’s also why a bedroom that’s still bright at 7:30pm in summer is working against you. Blockout blinds or a heavy curtain earn their money.
Physical tiredness. Straightforward, and the one everyone already knows. It probably does less work than parents assume. Plenty of children run hard all afternoon and still fight bedtime.
Mood and stress. A child who has run around is generally a calmer child at bedtime, and a calmer child falls asleep faster. This is the part the trial data supports most clearly: the 2025 review found exercise improved sleep anxiety and bedtime resistance, both of which are about state of mind rather than how tired the legs are.
Sleep and sports performance
Most of what’s written about sleep and sports performance comes from adolescent and adult athletes, where the evidence is reasonably strong. A narrative review of adolescent athletes found that sleep affects physical and cognitive performance, recovery, injury risk and mental wellbeing, and that athletes may need more sleep than the general population rather than less.
None of that transfers neatly to a seven-year-old at a Saturday class, and it would be a stretch to pretend otherwise. At this age nobody is managing training load or chasing marginal gains.
What does transfer, and what’s visible every week, is the softer stuff. Tired children have shorter fuses, slower reactions and less patience for the bit of a skill that takes three goes to click. They’re more likely to give up on a drill, more likely to end up in tears over a lost possession, and less likely to want to come back next week. The relationship between sleep and sports at this age shows up in enjoyment and persistence long before it shows up in anything you’d call performance.
It runs the other way too, which is the more useful half. Sports and sleep feed each other. A child who has been outside and active tends to settle better, and a child who has settled better turns up on Saturday actually wanting to play.
Is exercise before bed a bad idea?
This is the question that comes up most, and the answer is more specific than yes or no.
The Sleep Health Foundation advises steering clear of vigorous activity in the hour before sleep, and notes that outdoor exercise is useful precisely because it delivers movement and daylight at once. That hour is a narrow window. A 4pm class, or a Saturday morning game, sits nowhere near it.
What confuses parents is the wired-up child. Plenty of kids come home from a class buzzing, and it’s easy to read that as evidence the activity has wrecked bedtime. Usually it’s the excitement rather than the exercise, and it tends to settle once they’re home and the routine starts. A predictable wind-down (bath, quiet activity, same order every night) does more to resolve it than moving the class would.
If there’s genuinely a late evening session in the mix, keep the gap between finishing and lights out as long as you can, and make the wind-down deliberate rather than assuming exhaustion will do the job.
The overtired trap
More activity isn’t always better for sleep, and this is the thing worth saying loudest. Wearing a child out is a common strategy and an unreliable one. As sleep researchers explain it, a child pushed well past the point of tiredness becomes stressed, and stress is one of the things that stops people falling asleep. The evening can end up worse than if you’d done less.
There’s a version of this most weekends: three activities booked back to back, a child who was fine at 9am and is inconsolable by 2pm, and a bedtime that falls apart entirely. If a child is already active during the day and still fighting bedtime, adding more activity is unlikely to be the fix. Look at timing, wind-down and consistency first.
Screens and the hour before bed
Both healthdirect and Children’s Health Queensland advise avoiding digital devices in the hour or two before bed, and keeping them out of the bedroom where possible.
There’s a lot written about blue light and melatonin, and the mechanism is more debated than the popular version suggests. A 2024 review in Sleep Medicine Reviews, co-authored by researchers at Flinders University, found that the bright-light and arousal effects of screens have been studied extensively and show only a small impact. A bright screen or stimulating content delays falling asleep by around ten minutes at most. The bigger problem is simpler: screens push bedtime later and displace sleep outright.
The practical advice doesn’t change either way. Devices out of the bedroom, screens off well before lights out, quiet activities instead: reading, being read to, a bath.

A sleep-friendly weekday
Rough shape for a primary-aged child. Adjust the clock to suit your family; the order matters more than the times.
Time | |
7:00am | Consistent wake time, curtains open, breakfast in natural light |
8:15am | Walk at least part of the way to school |
3:30pm | Ten minutes outside before homework or screens |
4:00pm | Activity: a class, the park, the backyard |
5:30pm | Dinner |
6:30pm | Screens off, wind-down starts |
7:00pm | Bath, quiet activity, reading |
7:30pm | Lights out |
The load-bearing parts are the fixed wake time, the morning light and the gap between screens and sleep. Everything else can move.
Worth noting that the same guidelines covering sleep also recommend at least 60 minutes of moderate to vigorous physical activity a day for children aged 5 to 17, and it doesn’t have to happen in one block. A class, a walk to school and a run around the backyard all count towards it.
When to talk to your GP
Sleep hygiene helps a lot of children, and it isn’t the answer for all of them. Worth a conversation with your doctor if your child:
- Snores regularly, or you notice pauses or struggling in their breathing while asleep
- Is persistently difficult to settle despite a consistent routine
- Is excessively sleepy during the day
- Has sleep problems that are affecting school, mood or family life
More than one in three children have a sleep problem, and some of them have a cause that routine changes won’t touch. Asking is not an overreaction.
Soccajoeys runs non-competitive kids’ soccer classes for children aged 2.5 to 11, after school and on weekends. Most sessions finish hours before bedtime, and the calmer, less frazzled evening that tends to follow a class is where a lot of the benefit actually shows up.
