Sleep and bedtime routines for autistic children

Why do so many autistic children struggle to sleep?

Sleep problems are very common in autistic children. A review of the research concluded that "the majority" of autistic children are likely to have sleep difficulties, and that settling (getting to sleep) is the problem reported most often. In one study of children aged 3 to 10, 77.5% of autistic children were poor sleepers on a parent questionnaire, compared with 29.2% of non-autistic children. These figures come from outside the UK; we could not find a reliable UK-only figure.

When sleep is measured with a movement monitor or a sleep study, the gap is smaller. A meta-analysis of 10 studies found autistic children slept about 33 minutes less a day on average and took about 11 minutes longer to fall asleep. The shortfall in sleep time was clear in children who also had a learning disability, but small and not statistically significant in those without one.

There is rarely one cause (see the checklist below). Several studies have also found differences in the level or timing of melatonin, the body's own sleep hormone, in autism (Rossignol and Frye 2011).

What should I check first?

Check for physical causes and look at the bedroom before trying anything else. If an autistic child develops a sleep problem, NICE says professionals should offer an assessment that looks at (NICE CG170):

• what the problem is: trouble falling asleep, waking often, unusual behaviour, breathing problems or sleepiness in the day
• sleep patterns day and night, and whether bedtime is regular
• the bedroom: noise, a blackout blind, a TV or computer, and room sharing
• pain or discomfort, such as reflux, ear or toothache, constipation or eczema
• the effects of any medicines, and other conditions, especially ones involving hyperactivity
• daytime activity, and worries such as problems at school
• the effect on you and the rest of the family.

Constipation is much more common in autistic children than in other children (McElhanon et al. 2014). If your child cannot easily tell you that something hurts, a change in sleep may be one of the first clues. Our guide to toilet training lists the signs of constipation.

What help does the NHS offer for sleep problems?

NICE sets out a step-by-step route, and most of it comes before any medicine. This table sums up recommendations 1.7.4 to 1.7.8 of NICE CG170.

The research supports starting with a plan. A review of 11 studies involving 416 autistic children or children with a learning disability found that training parents in behavioural sleep strategies was "generally effective and valued by parents", with 9 of the 11 studies reporting fewer sleep problems.

How do I make a picture bedtime routine?

A good bedtime routine is short, calm and the same every night, and pictures let your child see what comes next. NICE recommends visual supports such as "words, pictures or symbols that are meaningful for the child", and says a sleep plan should aim for "a regular night-time sleep pattern".

1. Pick a start time you can keep most nights.
2. Choose 4 to 6 steps and keep them in the same order. For example: bath or wash, pyjamas, teeth, toilet, story, lights out.
3. Use pictures your child understands. If symbols mean little to your child yet, use photos or real objects, such as their own toothbrush (Autism Toolbox). Our visual timetable printable can hold the steps.
4. Put the pictures where your child can see them, such as by the bed. Go through them together, and let your child move each picture to "finished" when a step is done.
5. Make the last hour calm. Switch screens off for the hour before bed, as the Royal College of Paediatrics and Child Health advises. A UK government expert report on under-5s (2026) also recommends screen-free bedrooms.
6. Build in movement earlier in the day. A meta-analysis of 8 controlled studies found physical activity programmes had a large positive effect on parent-reported sleep problems in autistic children and teenagers, though there were only a few studies.
7. Give it time, and change one thing at a time, so your sleep diary can show what helps.

How can I make the bedroom easier to sleep in?

Look at the bedroom through your child's senses. Sensory differences are very common in autistic children, and the National Autistic Society lists bright lights, background noise, electrical humming, fabric textures and feeling too hot or cold among everyday triggers.

Some children find firm, heavy touch calming, such as a big hug (Derbyshire CAMHS). Our guide to sensory differences has more ideas.

What if my child wakes in the night, wakes early or won't sleep in their own bed?

Start with the same checks: pain, illness, the bedroom and your diary. Then pick one change and stick with it for a couple of weeks.

Waking in the night

• Look in the diary for patterns: the time, what happened that day, and what helped your child settle again.
• Respond the same calm way each time, with few words, low light and back to bed.
• If your child falls asleep with you beside them, or with a light or music on, they may look for the same thing when they wake. Try to make the room at bedtime look and sound the way it will at 2am.

Waking very early

• Check whether early light is waking your child. A blackout blind can help.
• Look at naps and bedtime in your diary.
• Give a clear picture signal for "time to get up", such as a lamp on a plug-in timer. Until it comes on, it is quiet time in bed with a book or toy.

Not sleeping in their own bed

There is no set age for sleeping alone. If sharing works for your family and everyone sleeps, it may not need to change now. If you want to change it, go gradually:

1. Show the plan in pictures or a short story, so the change is predictable. The National Autistic Society suggests preparing ahead and counting down to changes.
2. Start by sitting by your child's bed until they fall asleep.
3. Every few nights, move your chair a little further away, until you are outside the door.
4. Use the same few words each night, and praise your child in the morning.

See our guide to transitions and change for more on preparing for changes.

Do melatonin, weighted blankets or supplements help?

Melatonin can help some children, but in the UK it comes after a sleep plan, not before. Weighted blankets did not lengthen sleep in a UK trial, and NICE says not to use omega-3.

Melatonin

Melatonin is a hormone the body makes to help control sleep, and it is also given as a medicine. In the UK, melatonin is available on prescription only, and it is sometimes prescribed by specialists for longer-term sleep problems in children (NHS). A prolonged-release melatonin tablet is licensed in the UK to treat insomnia in children and young people aged 2 to 18 who are autistic (or have certain genetic conditions) "where sleep hygiene measures have been insufficient" (summary of product characteristics). Sleep hygiene means healthy sleep habits, such as a regular routine and a calm bedroom.

NICE says melatonin should only be used after consultation with a specialist paediatrician or psychiatrist with expertise in autism or children's sleep, alongside non-drug approaches, and with regular reviews to check the benefits still outweigh the side effects and risks. Ask your GP or paediatrician how this works where you live. Only give your child melatonin that has been prescribed for them, not products bought online or abroad, and ask the prescriber or a pharmacist if you have questions.

In the main trial of 125 children aged 2 to 17, whose sleep had not improved with behavioural approaches alone, children taking prolonged-release melatonin for 13 weeks slept on average 57.5 minutes longer, compared with 9 minutes on a placebo (dummy tablet); after statistical adjustment, the difference was about 32 minutes. They also fell asleep about 40 minutes faster, compared with about 13 minutes. Sleepiness was more common with melatonin. This was one trial, linked to the company that makes the product.

Weighted blankets

In a UK trial, 73 autistic children aged 5 to 16 with severe sleep problems used a weighted blanket and an ordinary blanket that looked the same, for 2 weeks each, and 67 finished. The weighted blanket "did not increase" total sleep time measured by a movement monitor, and made no difference to other sleep or behaviour measures. But parents and children preferred it, and it was well tolerated.

So a weighted blanket may be a comfort your child enjoys, but it is unlikely to help them sleep longer. The National Autistic Society says the Royal College of Occupational Therapists recommends that an occupational therapist assesses their use. The trial did not include children under 5, and The Lullaby Trust advises against weighted or bulky bedding for babies under 12 months.

Omega-3 and other supplements

NICE says: "Do not use omega-3 fatty acids to manage sleep problems in autistic children and young people." Ask your GP or a pharmacist before giving any supplement for sleep.

Who can help with my child's sleep?

Start with your GP, or your health visitor if your child is under 5. Ask for a sleep assessment, help with a sleep plan, and what sleep services there are locally. If sleep problems keep affecting your family, NICE says to consider referral to a paediatric sleep specialist and short breaks. Our guide to looking after yourself explains how to ask your council about short breaks.

Charities that can help:

• The Sleep Charity runs the National Sleep Helpline, 03303 530 541: Monday to Thursday 9am to 11am, and 7pm to 9pm on Monday, Tuesday and Thursday (as of September 2026). It helps parents of children aged 12 months and over, but cannot give medical advice and is not a crisis service. See The Sleep Charity.
• Cerebra's Sleep Advice Service has a sleep tips booklet, webinars and one-to-one support for families who meet its criteria, using two weeks of sleep diaries. Phone 01267 244 200. See Cerebra.
• Scope publishes sleep advice for families of disabled children. Its free Sleep Right service is for families of disabled children aged 2 to 18 who can travel to sessions in East London (Newham listing). See Scope.
• Contact's helpline for families with disabled children, 0808 808 3555, covers sleep among other topics. See Contact.

The NICE guideline is for England. Services in Scotland, Wales and Northern Ireland are organised differently, but you can still ask your GP about an assessment, a sleep diary and a sleep plan.
