Sleep isn't just rest for children — it's when growth hormone is released, memories are consolidated and emotional regulation develops. This guide pulls together everything parents need: how much sleep kids need at each age, why the first years are so rough, a bedtime routine that actually works, and when a weighted blanket can help.
How much sleep does a child need?
Sleep needs change dramatically through childhood:
- Newborn (0–3 months): 14–17 hours, in many short stretches.
- Infant (4–11 months): 12–15 hours, including 2–3 daytime naps.
- Toddler (1–2 years): 11–14 hours, dropping to one afternoon nap by age 18 months.
- Preschool (3–5 years): 10–13 hours. Most drop the nap around age 4.
- School age (6–12 years): 9–12 hours.
- Teenagers (13–18 years): 8–10 hours. Biological bedtime shifts later at puberty.
Children differ, but if a child is cheerful, alert and growing, they are probably getting enough — even if the number looks different to their friends.
Why one-year-olds sleep so badly
Roughly half of one-year-olds have sleep problems at some point — it is entirely normal. At this age:
- Sleep cycles are significantly shorter than adults' (50–60 min vs. 90 min), so waking between cycles happens often.
- Children have more stages of shallow sleep, meaning they are more easily woken by noise, thirst or discomfort.
- Developmental leaps — language, walking, emotional complexity — disrupt sleep even in previously "good sleepers".
- Separation anxiety peaks around this age, making it harder to fall asleep alone.
Most children grow out of it. What parents need in the meantime is a structure that helps everyone get as much rest as possible.
A sleep schedule that works
A sleep schedule is a set of regular times — waking, naps, feeds and bedtime — adapted to your child's age. Stable rhythms work because the body clock is reinforced by repetition.
- Keep wake-up time steady even on weekends. Late wake-ups push bedtime later.
- Match nap length to age: toddlers do best with a single 1–2 hour afternoon nap ending by 3 pm.
- Start bedtime cues 30–45 minutes before "asleep" time. Think bath → book → lights out, not "bed now".
- Protect the last hour: no screens, calm voices, dim lights. A screen-exposed brain fights sleep for an hour after.
Helping a child relax in the evening
Modern life is stressful for children too — school, friendships, screens, constant stimulation. A gentle wind-down isn't optional; it's what tells the nervous system it is safe to sleep.
Ten calming techniques
- Turn off screens at least 60 minutes before bed. Blue light suppresses melatonin; scary or exciting content keeps the brain alert.
- Warm bath — the post-bath temperature drop triggers drowsiness.
- Read together — nothing stimulating; familiar, comforting stories work best.
- Slow breathing — "breathe in for 4, out for 6" in a low voice alongside your child.
- Body-hug — tight snug under the covers; older kids can imagine "filling up" each limb with heaviness.
- Worry journal — five minutes to write or draw tomorrow's worries, then close the book.
- Low light — a warm-toned nightlight is better than total darkness for anxious children.
- Cool bedroom — 18 °C is a good target; kids overheat faster than adults.
- Predictable routine — same order every night. Security is sleep-promoting.
- Weighted comfort — a cuddly toy, a favourite blanket, or for older children a weighted duvet for steady calming pressure.
Most children simply grow out of bedtime difficulties. But if your child is afraid to fall asleep, has persistent night terrors, or you see serious daytime consequences, speak to your health visitor or GP.
Weighted duvets for children
A weighted duvet adds gentle, even pressure that feels like being held. For stressed, anxious or neurodivergent children (ADHD, autism), it can dramatically help falling asleep and staying asleep. Research shows the same mechanism as in adults: pressure raises oxytocin and serotonin, lowers cortisol, and helps melatonin release.
Choosing the weight for a child
Start from age, not body weight (children's surface area is smaller, so the per-kg calculation doesn't quite apply):
- 3–4 years → 3–5 kg
- 5–6 years → 5–7 kg
- 7–14 years → 7–9 kg
Do not use weighted duvets for children under 3. They must be able to push it off themselves.
Dr. Kerstin Malmberg, chief physician at Stockholm's child and adolescent psychiatry clinic, who has treated children with sleep problems for nearly 30 years, notes that the most common paediatric sleep disorder is insomnia — difficulty falling asleep, waking at night, waking too early or poor sleep quality. Weighted duvets are often a useful part of the toolkit, alongside routine and environment.
When to seek help
Most children's sleep problems are temporary. Consider talking to a professional if:
- Your child snores loudly, pauses breathing, or is extremely sleepy during the day — possible sleep apnoea.
- Bedtime resistance has lasted months and is affecting your child's mood or school performance.
- Your child has night terrors several times a week that they cannot be soothed out of.
- You as a parent are at the end of your capacity — you matter too. Sleep deprivation is serious.
Putting it together
No single tip fixes a child's sleep — a combination does. Keep the schedule steady, protect the wind-down, cool the room, and add tools like a weighted duvet if your child needs the extra calm. Sleep is a parenting marathon, not a sprint; small improvements compound into big ones.
