Please read this very carefully if you give melatonin to an autistic child every night…

I've sat with hundreds of autism parents in our support group. And when a parent tells me "the melatonin works, he's asleep by 8… but he's up at 2 and won't go back down," I already know what the next year looks like for that family.

The dose goes up. The 2am wake-ups don't go away. And the parent starts falling apart.

I know, because that parent was me.

My name is Katie McCall. My son is autistic, and for three years I gave him melatonin every single night.

It worked. He fell asleep. And at 2am, every night, the light came on under his door.

I thought those were two different problems. A sleep problem we'd solved, and a waking problem we hadn't.

They're not. They're one problem, showing up two different ways.

Here's what I wish someone had told me on day one

Melatonin is a signal. It tells the body "it's time to sleep." It does that job well. It helps a child drift off.

But it was never designed to keep a child asleep. It does its job at bedtime and then it fades. By the early hours, the signal is gone.

So the falling asleep gets "managed." The staying asleep never gets touched.

And nobody asks about 2am. Most appointments are a few minutes. "Is he sleeping?" "Yes, he's asleep by 8." Tick. Same melatonin. Come back in six months.

Nobody asks what happens at 2am. Nobody sees you at 2am.

But I hear about it every week from the parents in my group.

The mum whose 7-year-old was asleep by 8 every night "thanks to melatonin." Started on 1mg. Then 2. Then 3, when it "stopped working like it used to." Two years later she was sleeping on his bedroom floor, because if she didn't, he'd be in the kitchen at 3am emptying the cupboards. She told me she hadn't slept in her own bed since he was five.

The dad who said, "the paediatrician said we can double it." So they doubled it. He still woke at 1:30. Still singing. Still wired for four hours. The dad was going to work on three hours' sleep and missing shifts.

They don't complain at the appointments. They say "he's sleeping better."

But I know what they're losing.

My own story looked fine on paper, too

Asleep by 8. Every night. Melatonin gummy with his toothbrush.

And then the light under the door.

Him bouncing on the bed, scripting his favourite show, wide awake like it was morning. Me sitting outside his room on the landing in the dark, waiting to see if he'd settle. He never did.

I stopped going out in the evenings because I knew I'd be up at 2. I cried in the car before the school run more times than I can count. I started to believe it was my fault. That some other routine, some other blanket, some other bedtime story would fix it.

I'd tried it all.

Everything helped a little. The 2am wake-up never moved.

Because none of it was reaching whatever was waking him up.

Then I found out three things nobody had told me about the melatonin itself

I'm not telling you this because I'm against melatonin.

It got my son to sleep when nothing else could. For a lot of families it's the only thing that does. I'm not telling you to throw it away.

But it was never built to do the job I needed it to do. And I'd been asking more of it every year.

Here's what finally made sense to me

A child who falls asleep and then wakes at 2am fully alert isn't "not tired enough." Their nervous system is stuck on.

Think of it like a brake and an accelerator. At night, the brain is supposed to take its foot off the accelerator and press the brake. There's a brain chemical called glutamate, the "go" signal. It's supposed to quiet down at night.

But that brake runs on a mineral. Magnesium.

When magnesium is low, the "go" signal never fully switches off. The child can be pushed into sleep at bedtime, which is what melatonin does. But a few hours later, the smallest noise, a full bladder, a shift in the room, and the nervous system snaps straight back to "on." Wide awake. 100%. Ready to start the day.

And so many autistic kids are picky eaters, living on a handful of safe foods. That's exactly the kind of diet that runs low on magnesium. A big sensory day drains it even faster.

That's why the waking felt so random. It wasn't random. It was a nervous system with no brake.

So I went looking for a magnesium my son would actually take

That's harder than it sounds. A lot of children's magnesium uses magnesium oxide, the cheapest form, and the body absorbs very little of it. It's also the form most known for upsetting little tummies.

The gentle form is magnesium glycinate. Well absorbed, easy on the stomach.

And it had to be a gummy he'd actually eat, because anything that looked like medicine was going straight on the floor.

That's when I found Sweet Dreams.

• 1

  Magnesium glycinate THE HERO

  The gentle, well-absorbed form, to support the calm side of the nervous system.

• 2

  L-theanine

  The calming amino acid found in tea. Relaxed, without drowsiness.

• 3

  Passionflower

  A traditional botanical for winding down.

• 4

  Chamomile

  The classic bedtime botanical.

I didn't expect a miracle. I'd been let down too many times. But the logic made sense, and they had a 30-night guarantee, so I ordered it.

What happened next

1. Night 14:10am

   He fell asleep with his melatonin like always. He still woke, but at 4:10, not 2. I noticed. I didn't let myself believe it.

2. Night 52:30am

   He woke at 2:30, but he didn't get up. I listened at the door. He turned over. And he went back to sleep.

3. Week 26:15am

   I woke up at 6:15 to the sound of my alarm. Not to him. I lay there in the dark and didn't move, in case I'd jinx it.

4. Week 3All night

   My husband and I slept in the same bed for a full night for the first time in two years.

Editor note: the times and results above are placeholders. Replace them with a real customer's story before launch.

The mornings changed too. Fewer meltdowns at breakfast. He was calmer getting into school.

I started telling the parents in my group. The mum who slept on her son's floor messaged me three weeks later: "He slept through. I slept in MY bed." The dad who'd been missing shifts told me he'd stopped dreading Sunday nights.
