You're not imagining it
Sleep problems are very common in autistic children: trouble falling asleep, waking in the night, and waking very early. Many parents feel they've tried everything. It isn't a parenting failure.
Common reasons
Sensory sensitivity: a scratchy tag, a humming fridge, or a sliver of hallway light can be enough to keep a child alert.
Body clock differences: some children's natural melatonin rhythm runs differently, so they don't feel sleepy at the usual time.
Anxiety and transitions: bedtime means leaving a favourite activity and being alone in the dark, which can be hard.
Other health factors: reflux, constipation, allergies, or breathing issues can disrupt sleep and are worth raising with your doctor.
What often helps
Keep the same wake-up time every day, including weekends. It anchors the body clock more than bedtime does.
Dim lights and switch off screens about an hour before bed.
Use a visual schedule for the bedtime routine so each step is predictable.
Make the room sensory-friendly: dark, cool, quiet or with steady white noise, and soft bedding your child chooses.
Some children find deep pressure calming, such as a snug hug, compression sheet, or a correctly sized weighted blanket.
When to talk to a professional
If your child snores loudly, stops breathing in their sleep, is very sleepy in the daytime, or nothing has improved after a few weeks of steady routine, speak with your pediatrician. They can check for medical causes and refer you to a sleep specialist.
