Research estimates that 40-80% of children with ASD have trouble with sleep.


Many babies and children have sleep difficulties, especially with settling and night waking. In children with autism spectrum disorder (ASD), these problems can be more severe than in other children. You can manage and overcome many sleep problems in your child with ASD using common behaviour strategies.

Autism spectrum disorder and sleep

Like all children, children with autism spectrum disorder (ASD) can have trouble getting to sleep and staying asleep. Children with ASD can also have sleep problems that we don’t see as often in other children. These difficulties include: 

  • irregular sleeping and waking patterns – for example, lying awake until very late or early-morning waking
  • sleeping much less than expected for their age, or being awake for more than an hour during the night
  • getting up and playing, and making noise for one or more hours during the night
  • excessive sleepiness during the day.
Sometimes sleep problems last for a long time in children with ASD. Other times they improve as children get older.

Sometimes he wakes up too early and is unable to settle. Because he needs reassurance, he wakes the household.

Why children with autism spectrum disorder have trouble sleeping

Communication difficulties
Many young children with autism spectrum disorder (ASD) have trouble communicating their wants and needs to others. Your child might be kept awake by something he needs but can’t ask for. Also, because of their communication difficulties, children with ASD sometimes can’t pick up cues that bedtime is coming up.

Love of routine and bedtime habits
Children with ASD can be very attached to their routines and rituals. Your child might settle well if the regular bedtime routine is followed, but not otherwise. Also, children with ASD can get into the habit of falling asleep in a particular place, and they won’t settle anywhere else. Habits like these can be difficult to break for children with ASD.

Favourite objects and associations
Children with ASD might have favourite bedtime objects, or favourite pyjamas they need to wear, or a pillowcase they must have before settling. Without these objects and associations, some children with ASD can’t settle.

Other reasons: anxiety, hyperactivity, medical issues and medication
Children with ASD can have a lot of anxiety. This can make it hard for them to get to sleep, or get back to sleep after waking. Children with ASD also sometimes have hyperactivity and can stay very active and alert right into the evening.

Like all children, children with ASD can suffer from illnesses – colds or ear infections – that make it hard for them to settle or sleep well. Chronic illnesses such as asthma or epilepsy can also affect children’s sleep.

The side effects of some of the medications used for children with ASD can include trouble sleeping. 

If you’re having trouble working out why your child is having sleep problems, try keeping a sleep diary. By writing down your child’s sleeping behaviour, you might start to see a pattern, or notice something in the environment that could be affecting your child’s sleep. This will also be useful for any professionals working with you to help with your child’s sleep.

Managing autism spectrum disorder sleep difficulties

Sleep and settling difficulties in children with autism spectrum disorder (ASD) aren’t always part of having ASD. Some sleep problems are behaviour issues you can manage using strategies you’d use for any other child.

That said, your child with ASD might have difficulty understanding what you want her to do, and accepting any changes that you make. Dealing with your child’s sleep difficulties might need lots of time and patience on your part.

Here are some strategies for managing settling and night-waking difficulties.

Sleep routines and habits

  • Develop a positive bedtime routine you can use wherever you and your child happen to be.
  • Set a regular, age-appropriate bedtime for your child. It should be when you know your child will be sleepy, but not overtired. Many parents of children with ASD say that regular bedtimes and wake times are helpful for dealing with sleep problems. 
  • Make sure you give your child plenty of warning that bedtime is approaching. If your child doesn’t like to change activities with little warning, your child might get upset if you suddenly decide ‘it’s time for bed’.
  • Be consistent in how you warn your child that bedtime is approaching. You could use a cue like a clock or an appropriate picture to show your child it’s nearly bedtime. Choose something you can use or do wherever you are, including when you’re on holidays or at someone else’s house.
  • If your child gets upset and gets out of bed, quietly and calmly put her back to bed. You might need to do this many times, especially if you’re trying to develop a new bedtime routine. Many parents of children with ASD say that returning their child to bed is helpful for dealing with sleep problems.

Sleep environment

  • If your child won’t fall asleep without a particular object – for example, a toy, special pyjamas or pillows – try to think of ways to vary this. You might need to phase out the item, perhaps by gradually rotating different items at bedtime. This might stop your child from relying on just one.
  • Encourage your child to fall asleep in his own bed – not on the couch, in your bed or anywhere else. It’s also important for him to learn to fall asleep by himself. You might need cues to help your child understand that he needs to fall asleep in his bed by himself. These could be things like a picture showing him asleep in bed and you sitting watching TV.
  • If your child experiences anxiety about going to bed or sleeping alone, you could try wrapping your child in a blanket, using a nightlight in the bedroom, and/or playing music in his room when he’s in bed.

Other factors
If your child has been ill, she might keep wanting the extra attention she got when she was sick. When your child is better, try the settling strategies above again. But consult your child’s doctor if you think your child’s poor sleep is related to a medical problem – for example, asthma or epilepsy.

And if your child wakes during the night, calls out or gets out of bed, try the settling strategies above.

Other autism spectrum disorder sleep issues

Night terrors and nightmares
Sometimes children wake up screaming or crying. This could be caused by night terrors, which are normal in children from around 18 months to six years. Nightmares can also wake children up and make it hard for them to get back to sleep. Talk to your child’s doctor if you’re concerned or your child’s behaviour seems severe.

Bedwetting and toileting
Late toilet training and difficulties with toilet training are common in children with ASD. If your child isn’t dry at night, he might wake because he’s wetting the bed. Or he might wake to go to the toilet and then won’t go back to bed. 

You might consider getting some help if toilet training and bedwetting are problems for your child. For example, you could start by talking with your child’s early intervention workers. If there’s a persistent problem, also consult your child’s doctor.

Like all children, some children with ASD snore. If your child’s snoring is persistent and not associated with a cold or similar illness, consult your child’s doctor. Snoring can sometimes be a sign of sleep apnoea.

Restless sleep
Children with ASD sometimes have more restless sleep than other children. In particular, they might be prone to body-rocking, head-rolling and head-banging. Although quite common, restless sleep can also be a sign of some less common sleep disorders. It’s best to consult your child’s doctor if you’re concerned or your child doesn’t respond to settling strategies such as those above.

Children with ASD who don’t sleep well are more likely to have behaviour problems during the day. As with all children, persistent sleep problems can negatively affect the learning abilities of children with ASD. And research tells us that when children with ASD don’t sleep well, their parents are likely to experience poor sleep, high levels of stress and depression. So there are many good reasons for working on your child’s sleep habits.

Where to go for help

Sleep problems often start to get better after the first 2-3 nights of implementing settling tips such as those above. If you don’t see any improvement, there might be medical reasons for your child’s sleep problems.

You might need the support of a professional to use some of the strategies above, such as those based on gradually changing bedtime and wake time.

You should consult your health professional if the techniques you try don’t seem to help after the first few days. You might be referred to a paediatrician, psychologist or other health professional experienced in treating children’s sleep.

What about medication?
Before trying medication, it’s best to try the behaviour solutions suggested above. But medication has been found to be helpful for some children with ASD.

For example, some promising research shows that melatonin might help some children with ASD. Melatonin is a natural hormone in our bodies. Some children with ASD have lower levels of melatonin. Giving additional melatonin to these children can help them to fall asleep, stay asleep and have less difficult behaviour during the day. 

Melatonin can be prescribed only by a doctor. It shouldn’t be given to a child without medical advice and supervision.
