When bedtime stops being bedtime.

Why sleep gets harder for neurodivergent kids

Sleep difficulties are significantly more common in neurodivergent children — both those with ADHD and those with autism. The reasons vary.

A child with ADHD might have a brain that resists sleep onset; their nervous system stays activated when it should be winding down. Stimulant medication, if timed poorly, can delay sleep. Racing thoughts and difficulty "switching off" are typical.

A child with autism might struggle with the ritual break that bedtime represents. Transitions are hard. The sensory environment matters enormously — the texture of sheets, the exact temperature, the sound of the house shifting as it darkens. Anxiety about the unknown (falling asleep, what happens while they're asleep) can be significant.

Many children have delayed sleep phase — their circadian rhythm naturally runs later than their parents' or the school day's expectations. This is neurological, not naughtiness.

Sleep apnoea (breathing pauses during sleep) is also more common in neurodivergent children and is easy to miss. Look for loud snoring.

What's typical

Age-normed sleep needs are a guide, not a rule. Individual children vary. What matters is function, not hours.

• Under 5: typically 10–13 hours per 24 hours, often including a daytime nap.
• Primary school (6–12): typically 9–12 hours per night.
• Teens (13–17): typically 8–10 hours per night. Teenage circadian rhythms naturally shift later; fighting this is futile.

It is completely normal for children to resist bedtime, to call out for parents after lights out, to wake briefly in the night, and to take 15–30 minutes to fall asleep. Sleep is not binary; it is a process.

What is not typical, and what matters, is persistent patterns that affect daytime function or family wellbeing.

Patterns worth raising with your GP

When medication matters (and doesn't)

Melatonin is available on prescription in Australia. It is not a first-line treatment for sleep difficulties in children, but for children with significant sleep-onset delay — particularly those with ADHD or autism — it can be part of a plan.

Melatonin works best alongside behavioural strategies (predictable routine, wind-down, sensory optimisation). It is not a substitute for these. A paediatrician will prescribe a dose appropriate to your child's age and size, usually starting low and adjusting upward if needed.

Melatonin is effective for some children and ineffective for others. If a trial of 4–6 weeks doesn't show improvement, your doctor may adjust the dose or consider other options.

Sleep and ADHD medication

Stimulant medications (methylphenidate, dexamphetamine, lisdexamfetamine) can delay sleep onset, particularly if taken late in the day. Not every child is affected; individual response varies.

If your child is on ADHD medication and sleep has worsened, discuss timing with your paediatrician. Often, taking the medication earlier in the day — or adjusting the dose — resolves the issue. Some children sleep better once medicated because the medication reduces hyperactivity and racing thoughts.

Do not stop or adjust medication without discussing it with your paediatrician.

What actually helps — the boring version

Predictable wind-down. A consistent sequence 60 minutes before bed: low activity, dim lights, no screens, quiet voices. The same sequence every night. Your child's brain learns what comes next and begins to prepare.

Cool, dark, quiet. Room temperature around 16–18°C (cooler than the rest of the house). Blackout curtains. White noise or earplugs if external noise is an issue. Sensory environment is often the biggest lever.

Screens off 60 minutes before bed. Blue light suppresses melatonin. This matters. If screens are the only way your child calms, work with an occupational therapist to build alternatives.

Regular wake time (weekends included). This is more important than consistent bedtime. A wake time anchors the circadian rhythm. Sleep onset will follow.

Outdoor morning light. Exposure to natural light early in the day strengthens circadian rhythm. Even 15 minutes of outdoor time in the morning helps.

Lower parent stakes. Bedtime battles escalate sleep anxiety. The goal is calm, bored, boring. If bedtime has become a conflict zone, consider stepping back and rebuilding from a different angle — perhaps with a therapist or sleep coach.

Sensory at bedtime

For neurodivergent children, sensory environment can be the difference between sleep and no sleep.

Weighted blankets can help some children feel grounded and calm. They should be age-appropriate (a rough guide: 10% of body weight) and not so heavy they feel restrictive. Some children love them; others find them claustrophobic. Trial, observation, adjustment.

Pyjama texture matters. Some children need soft cotton; others need tight, compressive clothing. Some dislike labels or seams. Experiment and let your child guide you.

Bedding — thread count, weight, whether it's tucked or loose — affects whether sleep is possible. A child might not be able to articulate this; watch for fidgeting, complaint about the bed, or refusal to lie down.

Night lights. Some children need complete darkness to sleep. Others need a low-level light (red light is less disruptive than white or blue). Some benefit from knowing a light source is available if they wake.

An occupational therapist can help you systematically adjust sensory inputs.

The Australian pathway

Start with your GP. Describe the patterns, mention when they started, and note any daytime impact. Your GP can assess for sleep apnoea, discuss medication effects, and rule out other causes (reflux, restless legs, thyroid issues).

Your GP may suggest a sleep diary — a week of noting bedtime, wake time, and any wakings. This clarifies the pattern and helps a specialist assess.

If patterns persist, your GP can refer to a paediatrician or, in some states, a sleep physician. Public waitlists for paediatric sleep assessment can be long (6–12 months); private practitioners are faster (2–8 weeks).

If sleep apnoea is suspected (loud snoring, breathing pauses, daytime sleepiness), ask your GP for an ENT referral. Sleep apnoea is common in neurodivergent children and is treatable.

If anxiety is driving the sleep difficulty, a psychologist via Medicare Mental Health Care Plan (item 2715) can provide behavioural support — up to six subsidised sessions per year. Cognitive-behavioural therapy for insomnia (CBT-I) is evidence-based and effective.

An occupational therapist can help optimise sensory environment and bedtime routine, especially for children with autism or sensory sensitivities. Some sessions may be covered through NDIS if your child has an active plan.
