It's 9pm. Your child has been awake since 6am. They're clearly exhausted — you can see it in their eyes. And yet, here they are: bouncing off the walls, asking for water, needing one more hug, suddenly very interested in telling you everything they know about Minecraft.

You've tried the routine. You've limited the screens. You've done the warm bath, the lavender spray, the white noise machine.

And still, sleep doesn't come easily.

If this is your life, I want you to know something important: this is not a parenting problem. This is a nervous system problem.

When we talk about ADHD, we often focus on what happens during the day — the difficulty concentrating, the impulsivity, the big energy. But ADHD affects the brain around the clock, and bedtime is one of the hardest times of day for many children with ADHD.

Here's what's actually happening:

The ADHD brain seeks stimulation. The same wiring that makes it hard to focus on boring tasks makes it hard to settle into quiet stillness. When the environment slows down at night, the ADHD brain can actually feel more alert — because it's no longer being stimulated by the busyness of the day.

Melatonin release is often delayed. Research suggests that many children with ADHD have a delayed circadian rhythm — meaning their brain's signal to wind down and produce melatonin happens later than it does for neurotypical children. This isn't something they can push through or choose to change. It's biology.

Racing thoughts. Once the noise of the day drops away, many ADHD brains flood with thoughts, ideas, worries, and plans. The quiet that's supposed to help them sleep actually gives all those thoughts more space to run.

The body hasn't discharged enough. The nervous system of a child with ADHD is often still carrying the arousal load of the day — the over-stimulation, the emotional dysregulation, the effort of holding it together at school. Without support to discharge that load, it's very hard to settle.

When we understand what's actually happening in the ADHD brain at night, the bedtime battles start to make sense.

The resistance isn't defiance. The second wind isn't manipulation. The inability to "just lie still" isn't a choice.

What looks like a behaviour problem is often a nervous system that hasn't found a way to feel safe and settled enough to rest.

This is why strategies that work for neurotypical children often fall flat. Generic sleep advice — consistent bedtimes, limiting screens, a warm bath — can be helpful, but they don't address the underlying nervous system state that's making sleep hard in the first place.

What Can Actually Help

As a paediatric occupational therapist, I approach sleep through the lens of nervous system regulation. Rather than trying to enforce sleep, we look at what the body needs to feel safe and settled enough to allow sleep.

Some things that can genuinely shift the picture for children with ADHD:

Proprioceptive (heavy work) activities before bed. Things like jumping on a trampoline, carrying something heavy, doing wall push-ups, or being wrapped firmly in a blanket give the nervous system strong physical input — which has a calming, organising effect. This isn't about tiring your child out. It's about giving their body the sensory input it needs to downregulate.

A predictable transition period, not just a routine. The 30–60 minutes before bed matters as much as the bedtime itself. Gradual dimming of lights, lowering the noise level in the house, and moving toward slower activities helps signal to the nervous system that a shift is coming.

Environment that supports their sensory profile. Some children with ADHD need more input to settle — a weighted blanket, something to fidget with in bed, or white noise. Others are highly sensitive to light or sound. Understanding your child's sensory profile is key.

Co-regulation before expecting self-regulation. A calm, connected adult presence can help regulate a child's nervous system. This doesn't mean lying with them for two hours every night — but it does mean the bedtime connection matters.

If bedtime battles have been going on for months, if sleep deprivation is affecting your child's learning and mood, or if you've tried everything and nothing seems to shift — it's worth getting specialist support.

A paediatric occupational therapist can assess your child's sensory profile, look at what's happening across their whole day (not just at bedtime), and work with you to build an approach that's designed for their nervous system — not a generic one.

You don't have to keep guessing. And you don't have to do this alone.
