Walk through the children's vitamin aisle and melatonin looks pretty harmless. In fact looks promising!

It's sold in gummies. It's labeled for kids. It's “natural.” You don't need a prescription.

So I understand why parents assume it's a pretty safe thing to try when their child struggles with sleep.

I would NOT make that assumption.

Melatonin is a hormone that our brains naturally produce as part of the system that regulates when we sleep and wake. And despite how casually it's sold and used, there are still important questions about giving supplemental melatonin to children—particularly when it's being given night after night.

We don't have great long-term safety data in children.

The amount of melatonin in a supplement may not match what's printed on the label.

And most importantly, a child having trouble sleeping is not, by itself, a reason to give them melatonin.

Before we try to make a child fall asleep or stay asleep or sleep in, we need to understand why they're having trouble sleeping in the first place.

We don't have great data on long-term use in children

This is probably my biggest hesitation with casual, nightly melatonin use.

Short-term use appears to be reasonably well tolerated for many children. But many children aren't taking melatonin for a few nights.

They're taking it every night for months or years.

And our long-term safety data simply aren't as strong as I'd want them to be.

Some studies following children for a few years have been reassuring, including studies that haven't found clear effects on growth or pubertal development.

But the research is limited. We don't have robust evidence allowing us to say that years of nightly melatonin use is harmless for children.

That doesn't mean long-term melatonin has been shown to be dangerous.

It means we don't know enough.

I think that's important information for a parent making a decision about something their child may be taking every night.

You may not be giving the dose you think you're giving

This one surprises a lot of parents.

In the United States, melatonin is regulated as a dietary supplement rather than as a prescription medication.

Researchers tested 25 brands of melatonin gummies sold in the U.S. in a 2023 study.

Twenty-two were inaccurately labeled.

Among the products that contained melatonin, the actual amount ranged from 74% to 347% of what the label said.

One contained no detectable melatonin at all.

So even when a parent tells me, “We're only giving 1 mg,” there can be uncertainty about how much melatonin is actually in that gummy.

Then there's the question I care about most

Why isn't your child sleeping?

“My child can't sleep” can describe a lot of very different things.

Maybe your preschooler isn't tired because bedtime is too early.

Maybe bedtime has gradually turned into an hour of requests and negotiations.

Maybe your teenager's internal clock has shifted later.

Maybe anxiety is keeping them awake.

Maybe your child is snoring and their sleep needs to be medically evaluated.

Maybe the schedule simply doesn't leave enough time for sleep.

Those problems don't have the same solution.

Giving a child melatonin without understanding what's happening with their sleep can mean treating the symptom while missing the reason it's happening.

Does melatonin work?

Sometimes.

There is evidence that melatonin can improve sleep in some children. There is stronger support for its use in certain populations and for certain sleep and circadian problems, including some children with neurodevelopmental conditions.

The research in otherwise healthy children with insomnia is much less compelling than the ubiquity of children's melatonin products might suggest. Reviews have found some improvement in sleep, but the quality of the evidence is limited, and experts do not recommend jumping to melatonin as the first treatment for an otherwise healthy child with chronic insomnia.

That's an important distinction.

The question isn't simply whether melatonin can make a child fall asleep.

It's whether melatonin is an appropriate treatment for this child and this sleep problem.

This is why I'd talk to your child's doctor first

I know “ask your pediatrician” can sound like the obligatory disclaimer at the bottom of every health article.

Here, I actually mean it.

Your pediatrician can help determine whether there's something medical contributing to the sleep problem, whether melatonin makes sense for your child, and what dose and timing would be appropriate if it does.

Timing matters because melatonin is involved in regulating the circadian clock. Using it to shift the timing of sleep is different from simply giving a gummy at bedtime because a child isn't falling asleep.

There are absolutely situations in which a pediatrician or sleep specialist may recommend melatonin.

I just wouldn't make that decision based on the fact that it's available over the counter.

One more thing: store it like medication

Melatonin gummies look and taste like candy.

Children notice that too.

Between 2012 and 2021, U.S. poison control centers received more than 260,000 reports of pediatric melatonin ingestion.

Most children had no symptoms or mild symptoms, but hospitalizations and serious outcomes did occur.

If you have melatonin in your home, keep it somewhere children cannot access it.

So, should you give your child melatonin?

I tend to lean pretty strongly toward no.

There are absolutely situations where melatonin can be useful and appropriately recommended by a pediatrician or sleep specialist.

But for an otherwise healthy child who is struggling with sleep, I want to understand what's getting in the way before we give them something to make sleep happen.

There's another piece of this that matters to me too.

I don't love teaching children from a young age that they need to take something in order to sleep.

I work with adults who have spent years believing they can't sleep without a medication, supplement, perfect routine or some other thing they've come to rely on at bedtime. That belief can become incredibly powerful—even when their body is completely capable of sleeping without it.

Sleep is something our bodies already know how to do.

So before handing a child a gummy every night, I'd want a damn good reason for doing it.

And I'd want their pediatrician involved.

Struggling with your child’s sleep?

You don’t have to face it alone.
