Why your neurodivergent kid can't "just go to sleep"

Written By Katie Black

It's 10:47pm.

Your kid is still awake. You're sitting in the hallway. Again.

You've done the bath. The books. The lavender lotion. You've removed screens, kept bedtime consistent, made the room dark. You've done everything the sleep articles say to do.

And still: they're staring at the ceiling. Or calling for you. Or suddenly starving even though dinner was two hours ago.

You're exhausted. You're frustrated. And somewhere underneath that, you're worried something is wrong.

Here's what I want you to know: You're not failing at bedtime. Your kid's brain is working on a completely different schedule.

This isn't a discipline problem. It's biology.

Too tired to read the whole thing? Here's the short version:

Up to 80% of kids with ADHD and autism have sleep problems. It's not willpower. ADHD brains release melatonin late (sometimes 45-90 minutes late). Autistic brains often produce less melatonin overall.

What actually helps:

  • Morning light (10-15 min outside before 9am)

  • Sensory modifications (cool room, right textures, white noise)

  • Predictable routines with some flexibility built in

  • Melatonin can help—but talk to your pediatrician first

Standard sleep advice works for most kids. But your kid might need personalized modifications. Keep reading for the research and practical details.

Two different patterns, same exhausted parent

Here's where it gets useful.

ADHD brains typically have delayed melatonin. The sleep signal comes—it just comes late. Their internal clock is shifted forward.

Autistic brains often have reduced melatonin production overall. It's not just late. There may be less of it, period.

Both lead to you sitting in the hallway at 11pm wondering what you're doing wrong. (You're not doing anything wrong.)

But understanding which pattern fits your kid can help you figure out what might actually help them.

Why the standard advice isn't working

You've probably heard it all: consistent bedtime, dark room, no screens, avoid caffeine, establish a calming routine.

This advice isn't wrong. Research shows sleep hygiene changes do help most kids with ADHD (Psychology, Health & Medicine, 2020).

But here's what the research also shows: neurodivergent kids often need to personalize the standard rules.

A study on autistic adolescents found something important (Pavlopoulou, 2020):

  • Some kids need specific textures of pajamas and bedding (that tag you keep forgetting to cut out? It matters)

  • Holding a comfort object helps some kids feel where their body is in space

  • Engaging in focused interests before bed, even screens, can actually help some neurodivergent kids transition to sleep

  • Predictability and feeling emotionally safe matter as much as the physical environment

The researchers concluded that healthcare providers should "go beyond providing mainstream sleep hygiene rules" and instead work with neurodivergent kids to build personalized sleep habits.

Translation: the rules are a starting point, not a prescription. What works for your kid might look different than what the articles say.



What actually helps (based on research)

Morning light

This one surprises people, but it's powerful.

A week of natural morning light exposure can shift melatonin onset earlier by about 2.6 hours (Frontiers in Psychiatry, 2025).

What this looks like: 10-15 minutes outside in the morning, ideally before 9am. Even on a cloudy day, outdoor light is stronger than indoor light. If mornings are impossible, a light therapy lamp can help.

This tells your kid's brain: "The day has started. Start the clock."

Sensory modifications

For neurodivergent kids, the bedroom environment often matters more than it does for neurotypical peers.

The Autism Treatment Network's Sleep Toolkit recommends:

  • Cool, dark, quiet room

  • Attention to textures (pajamas, sheets, blankets—yes, all of it)

  • White noise or a fan to mask unpredictable sounds

  • Weighted blankets for kids who benefit from deep pressure

The key is experimentation. Some kids need complete darkness; others need a dim nightlight. Some need silence; others need steady background noise. You know your kid. Trust that.

Predictable routines (with flexibility)

Routines help. But rigid adherence to a script can backfire.

Keep the sequence consistent: bath, then pajamas, then book, then lights out.

Allow flexibility in the content: which book, how long, what comfort object, how many songs.

Visual schedules can help some kids understand and anticipate what's coming. Others do better with verbal cues. Again, you know your kid best.

When melatonin might help

The American Academy of Neurology's guidelines for autistic children recommend:

  1. Try behavioral strategies first. Environment and routine changes should be the starting point.

  2. Consider melatonin if those aren't enough. Research shows it can reduce time to fall asleep and increase total sleep.

  3. Use pharmaceutical-grade if you can find it. Over-the-counter melatonin varies widely in actual content.

  4. Talk to your pediatrician. Melatonin is a hormone. Short-term use appears safe, but long-term data in kids is limited.

For ADHD specifically, research shows that low doses (as low as 0.5-1mg) can shift the circadian rhythm earlier (MDPI Children, 2023). Timing matters: 1-3 hours before the desired sleep time works better than right at bedtime.

Important: This isn't medical advice. Please talk to your child's doctor, especially if they take other medications.

The screen question

You knew this was coming.

Standard advice says no screens for an hour before bed. The science on blue light and melatonin suppression is real.

AND

Research on autistic adolescents found that for some kids, engaging in a focused interest before bed, including screen-based activities like Minecraft, actually helped them transition to sleep (Pavlopoulou, 2020).

The researchers noted: "Such activities feel familiar, comforting and predictable… it is not real life, and that is the best thing about it."

This doesn't mean unlimited screen time is fine. But a blanket "no screens ever" rule might not work for your kid. Finding what genuinely calms your child matters more than following generic advice.

If you keep screens before bed, consider:

  • Blue light glasses or night mode settings

  • Calmer content (building games vs. fast-paced videos)

  • A clear endpoint so there's still transition time before lights out

Why this matters for tomorrow morning

Here's something parents don't always connect: better sleep leads to better mornings.

When kids fall asleep more easily and sleep more deeply, they:

  • Wake up easier

  • Have better emotional regulation

  • Can access their executive function skills

  • Are more available for learning and connection

The 11pm battles you're having now directly affect the 7:15am battles you'll have tomorrow. Solving one helps solve the other.

When to get more help

If you've tried these strategies consistently for 2-4 weeks and sleep is still significantly disrupted, talk to your pediatrician or a sleep specialist.

Sleep problems in neurodivergent kids can sometimes be connected to:

  • Anxiety or depression

  • Sleep apnea or breathing issues

  • Restless leg syndrome

  • Medication effects (especially stimulants)

  • GI issues

A thorough evaluation can rule out other contributors and help you build a more targeted plan.

The bottom line

Your kid isn't choosing to stay awake. Their brain is wired differently, and sometimes that wiring makes sleep genuinely harder.

Two things are true: This is real biology, AND there are things that can help.

Understanding the science doesn't fix everything. But it can help you stop blaming yourself, or them, and start problem-solving based on how their brain actually works.

Sleep is foundational. When it's off, everything else is harder. For them and for you.

You're not failing at bedtime. You're parenting a kid who needs a different approach. And now you have some places to start.
