For many parents of children with neurodevelopmental disorders (NDDs), bedtime can be one of the most challenging parts of the day. A child may take hours to fall asleep, wake repeatedly through the night, become distressed when asked to go to bed, or wake up long before the rest of the family. Some children appear energetic despite having slept very little, while others struggle with irritability, inattention or emotional outbursts the following day.

Over time, these difficulties can leave the entire family exhausted. Parents may wonder whether they are doing something wrong or whether poor sleep is simply part of their child’s diagnosis.

The reassuring news is that sleep difficulties are common in children with neurodevelopmental disorders, but they should not automatically be accepted as inevitable. Understanding why a child is struggling to sleep is the first step towards helping the child and the family rest better.

Why is sleep so important for a developing brain?

Sleep is not simply a period when the body rests and the brain switches off. It is an active biological process that supports brain development, learning, memory, emotional regulation and physical health.

During childhood, the brain is constantly developing new connections and refining existing ones. Sleep helps consolidate learning and supports the regulation of attention, mood and behaviour. A well-rested child is generally better equipped to manage frustration, participate in school activities, learn new skills and cope with everyday demands.

When sleep is insufficient or repeatedly disrupted, children may become irritable, restless, impulsive or emotionally overwhelmed. They may have difficulty concentrating, following instructions or managing changes in routine.

These effects can be particularly challenging in children who already experience difficulties with communication, attention, sensory processing or emotional regulation.

For example, a child with autism who has slept poorly may find ordinary sounds, transitions or demands much harder to tolerate the next day. A child with ADHD may appear even more restless and inattentive. These behaviours do not necessarily mean that the underlying condition has worsened; inadequate sleep may be contributing to the difficulties.

Why do children with NDDs experience sleep problems?

Sleep difficulties are frequently reported in autism, ADHD, intellectual disability and other developmental conditions. However, there is no single explanation that applies to every child.

Biological factors: 

The body’s internal clock, which helps regulate sleep and wakefulness, may operate differently in some children. Some experience difficulty becoming sleepy at an appropriate time or maintaining a regular sleep schedule.

Sensory differences: 

Children who are sensitive to light, sound, touch, temperature or clothing textures may find it difficult to settle in their sleeping environment. Others may seek particular sensory experiences to feel comfortable enough to fall asleep.

Anxiety and emotional regulation: 

Worries about separation, changes in routine, darkness or anticipated events may make bedtime stressful. Children who find it difficult to communicate their fears may express distress through crying, resistance or repeated requests for reassurance.

Medical problems: 

Pain, constipation, reflux, eczema, seizures, breathing difficulties and certain medications can interfere with sleep. Snoring and obstructed breathing, in particular, should never be dismissed as ordinary childhood sleep problems.

Daily routines and environmental factors: 

Irregular bedtimes, long or late naps, insufficient daytime activity, bright evening light and stimulating screen use close to bedtime can make sleep more difficult.

Often, several of these factors occur together. A child may have an underlying circadian rhythm difficulty, become anxious about bedtime and develop a pattern of needing a parent beside them to fall asleep.

This is why simply telling a child to go to bed earlier may not solve the problem.

Recognising the type of sleep problem

Parents may describe the problem as “my child does not sleep,” but understanding the specific difficulty helps determine what support is needed.

• Difficulty falling asleep: The child remains awake for a long time despite going to bed.
• Frequent night waking: The child wakes repeatedly and may need parental help to return to sleep.
• Very late sleep timing: The child becomes sleepy much later than the family schedule allows.
• Early morning waking: The child wakes too early and cannot return to sleep.
• Restless sleep: The child moves excessively, appears uncomfortable or repeatedly changes position.
• Snoring or breathing difficulties: The child snores loudly, gasps, breathes through the mouth or has pauses in breathing.

Keeping a simple sleep diary for one to two weeks can be helpful. Record bedtime, estimated time taken to fall asleep, night waking, morning waking, naps and daytime behaviour. This can reveal patterns that are difficult to recognise from memory alone.

What can parents do to improve sleep?

There is no universal bedtime strategy that works for every child. The goal is to understand the child’s needs and establish a predictable, supportive routine.

1. Establish a consistent wake-up time. A reasonably regular morning wake-up time helps strengthen the body’s internal clock. Weekend schedules should not differ dramatically from weekdays.

2. Create a predictable bedtime routine. Choose a short sequence of calming activities, such as bathing, changing into comfortable nightwear, reading a familiar story and dimming the lights. Visual schedules may help children who benefit from structure and predictability.

3. Adapt the environment to the child’s sensory needs. Consider whether the room is too bright, noisy, warm or cold. Comfortable clothing, familiar bedding, reduced noise or a preferred soothing object may help. The aim is not to impose a perfect bedroom but to create an environment in which the child feels safe and comfortable.

4. Manage screens and evening stimulation. Bright light and exciting content close to bedtime may delay sleep. Establish a realistic screen-free period before bed and replace stimulating activities with calmer alternatives.

5. Encourage daytime movement and natural light. Outdoor activity and morning daylight help regulate sleep–wake rhythms. Physical activity should suit the child’s abilities and preferences. Long or late afternoon naps may need adjustment if they interfere with nighttime sleep.

6. Respond calmly and consistently to bedtime difficulties. Repeated negotiations, unpredictable responses or activities that become more rewarding than sleep can unintentionally maintain bedtime struggles. A gradual, compassionate approach is usually more helpful than punishment, threats or forcing a child to remain in bed while highly distressed.

Children differ in their ability to understand routines and communicate their needs. Strategies should therefore be adapted to developmental level, communication abilities and family circumstances.

When should parents seek professional help?

Seek advice from a child psychiatrist, paediatrician or the child’s treating clinician when sleep problems persist, significantly affect daytime functioning or place considerable strain on the family.

Professional assessment is particularly important if the child snores loudly, gasps during sleep, has pauses in breathing, experiences unusual nighttime episodes suggestive of seizures, reports pain, or has severe restless sleep or excessive daytime sleepiness.

A clinician can review the sleep history, medical conditions and medications, and decide whether investigations or referral to a sleep specialist, ENT specialist or neurologist are needed. A sleep study is useful for certain conditions, such as suspected obstructive sleep apnoea, but is not routinely required for every child who struggles to sleep.

Melatonin may be appropriate for some children, particularly those with persistent sleep-onset or circadian timing difficulties. However, it is not a universal solution. Its suitability, formulation, timing and dose should be discussed with a qualified clinician. Parents should avoid independently starting medication, increasing doses or using adult sleep products for children.

Looking after the family matters, too

Persistent sleep difficulties affect more than the child. Parents may experience exhaustion, reduced concentration, stress and difficulties balancing work, caregiving and the needs of other family members.

Seeking help is not a sign of parenting failure. Nor does a child’s difficulty sleeping necessarily mean that the family routine is inadequate. Biological, developmental, medical and environmental factors may all contribute.

Parents should be encouraged to seek practical support, share caregiving responsibilities where possible and work with professionals who understand neurodevelopmental differences.

A final thought

Sleep is not a luxury or a secondary concern in neurodevelopmental care. It is an important part of a child’s health, learning, emotional wellbeing and daily functioning.

The most useful question is not simply, “How do I make my child sleep?” It is, “What is making sleep difficult for my child, and what support would help?”

With careful assessment, realistic routines, appropriate environmental adjustments and professional guidance when needed, many sleep difficulties can be improved.

Better sleep will not eliminate every developmental challenge, but it can help children feel better, participate more fully in daily life and give families a much-needed opportunity to rest.
