Sleep problems are extremely common in children with autism and ADHD, and they have a direct and measurable impact on mood, regulation, and behaviour during the day.

How Sleep Affects Behaviour

When children do not get enough sleep, the brain's prefrontal cortex — responsible for impulse control and emotional regulation — is the first to be affected. This means lower tolerance for frustration, more intense emotional responses, greater sensory sensitivity, and more meltdowns or shutdowns. Many children who appear to have a “behaviour problem” during the day are actually operating on insufficient sleep.

Common Sleep Issues in Children with Autism and ADHD

• Difficulty falling asleep due to a racing mind or sensory discomfort
• Waking during the night and being unable to resettle independently
• Early morning waking
• Resisting the bedtime routine with escalating behaviour
• Irregular sleep patterns

Can a Behaviour Support Practitioner Help?

Yes. Where sleep difficulties are contributing to behaviours of concern, a practitioner can assess the function of the bedtime resistance, develop a structured gradual bedtime routine, recommend environmental modifications (lighting, sound, sensory inputs), coordinate with occupational therapists or paediatricians, and coach parents through implementing changes consistently.

Is Sleep Support Funded by NDIS?

Where sleep difficulties are related to a participant's disability and impact daily functioning, this work can be funded under Capacity Building — Improved Daily Living.
