Is Melatonin Safe for Children? The Dangers Every Parent Needs to Know

Some nights, no matter how hard you try, your child just won’t fall asleep. The lights are off, the bedtime routine is done, and yet… they’re still wide awake. If you’ve ever found yourself pleading for sleep while your toddler asks for a fifth glass of water or “just one more story,” you’re definitely not alone.

In those exhausting moments, it’s so tempting to reach for melatonin gummies as a quick sleep fix — trust me, I’ve done this before myself. But as common as children’s melatonin supplements have become, you may have this voice in the back of your mind making you feel uneasy about relying on them.

And for good reason – experts have raised serious concerns about giving young children synthetic melatonin. In fact, melatonin is now the second-most popular “natural” supplement that parents give their kids after multivitamins, and with that boom in use has come a sharp rise in overdoses and emergency room visits involving children. Really.

In this article, I’ll share what I’ve learned about the risks of melatonin use in children, the growing number of overdoses, and the safer, food-based alternative that has made a huge difference for our family.

Melatonin Overdose in Children is Skyrocketing

A recent CDC study found that between 2012 and 2021, reported melatonin ingestions in children skyrocketed by 530%, totaling over 260,000 cases. Now, most of these were toddlers who accidentally got into the gummies (they look and taste like candy and in my observation, typically have no child-safe caps on the bottles). Thankfully, the majority of kids were okay, but some had scary symptoms – and in a few rare instances, severe overdose led to children needing ventilators, and even two fatal cases.

When children’s melatonin bottles are designed to appeal to children, can you blame a child for wanting to get their hands on these delicious-tasting gummy supplements? (Trust me, they’re delicious.)

For example, the L’il Critters brand of children’s melatonin appeals to children with its use of popular TV characters on the bottle (PJ Masks), a “SOOOO YUMMY!” claim on the packaging, and character-shaped gummies (Catboy, Gekko, and Owlette). (How did this get through legal review and quality assurance?!) Perhaps the reason children are reaching for melatonin gummies is not only because they’re tasty but also because there is usually no child-safety cap and because these products are subconsciously appealing to children. (This brand was the worst offender I encountered online, by the way. This doesn’t mean this is the brand that children were accidentally consuming, but it was the most appealing product to children. Other brands made their products look like they were made for children, but weren’t so outright egregious in marketing them to children.)

Other Dangers of Melatonin for Children

And in addition to the risk of accidents and accidental overdose of melatonin, there are other reasons to be cautious with supplementing melatonin (or not to do it at all!).

❌ Quality Concerns in Supplementing Melatonin: Because it’s sold as a supplement, there can be varying quality concerns. One analysis found that many melatonin products don’t contain what the label claims – some had less than half the advertised amount, while others had over four times the dose (especially in kid-friendly gummies). 😱 That means you could be giving your child a much higher (or lower) dose than you think.

❌ Melatonin Use for Children is Unnecessary: Experts also advise against using melatonin for most toddlers without a doctor’s guidance. For instance, doctors at Boston Children’s Hospital note that healthy children under three usually don’t need melatonin at all – their sleep difficulties are almost always behavioral (think inconsistent routines or bedtime resistance) and best solved with non-medical approaches. (I have an affordable holistic sleep coaching program that is just for this kind of thing.)

❌ Side Effects Involved With Giving Melatonin to Children: There are also side effects to consider, like headaches, bad dreams, night sweats, or morning grogginess. Melatonin is known to cause severe grogginess and exhaustion, even after waking. We also don’t know if this disrupts a child’s natural ability to produce their own melatonin and sleep naturally without a melatonin supplement.

❌ Unnecessarily High Dosage in Children’s Melatonin: As a 5’7″ female, I have had excellent sleep success using a microdose of 0.3mg (300 micrograms) of melatonin. But popular over-the-counter children’s melatonin supplements have anywhere from 0.5mg to 1.5mg of melatonin listed on the label… that is absurdly high! Children of any age don’t need this much melatonin and these popular children’s melatonin supplements should simply be avoided.

Out of 17 children’s melatonin supplements I looked at, 12 contained 1mg per gummy, 4 contained 0.5mg per gummy, and 1 contained 1.5mg per gummy. Not a single product I looked at contained less than 0.5mg per gummy. This is WAY too much melatonin for a child’s body, whether they are 4 or 12.

❌ The Long-Term Effects Are Unknown: We simply don’t have long-term research on how daily melatonin might affect a child’s development. Ongoing concerns exist because some animal studies hint that melatonin could affect puberty-related hormones, though there’s very little evidence of this in humans, and no long-term trials in kids have been done yet.

❌ Children Begin to Associate Sleep with Taking Supplements: When kids take a sleep supplement every night, are we unintentionally teaching them that they need a pill to fall asleep? This isn’t about occasional use — it’s about the messaging we send with consistent supplementation.

Given these concerns, it’s no surprise that we, as parents, should shy away from giving melatonin to children. While it’s best to not intervene with sleep at all, and I fully believe in a holistic sleep approach, I can personally attest to wanting to have something to give my children to help them sleep better every now and then. For example, when we’ve just come back from a trip or are getting over an illness and sleep is being disrupted.

So what’s a parent to do? Instead of melatonin, there are a few gentler, naturally effective options worth considering, including making your own homemade tart cherry gummies.

Natural Alternatives to Melatonin for Kids

If you’re looking for safer, gentler ways to support your child’s sleep on occasion — without turning to melatonin supplements — there are options. In fact, there are several natural remedies and sleep-supporting habits that can help your child wind down at bedtime and sleep more soundly through the night.

Here are some of my favorite melatonin alternatives for kids:

1. Tart Cherry Juice or Tart Cherry Sleep Gummies: My concerns about giving melatonin to my children led me to discover tart cherry juice, which is basically an all-natural melatonin alternative. Tart cherries are one of the few foods that naturally contain melatonin. They also contain tryptophan and other sleep-supportive nutrients that may help the body produce and regulate melatonin more gently. I love turning tart cherry juice into homemade sleep gummies — they feel like a bit of a treat but without the mystery ingredients or high doses found in store-bought sleep aids.

2. Magnesium Baths: A warm bath alone can help calm an overstimulated child — but when you add magnesium-rich Epsom salts or magnesium flakes, it becomes even more effective. Magnesium is known to support relaxation and calm the nervous system. Just 1/2 cup in a warm bath before bed can make a big difference, or you could even turn the bath into a detox bath by adding a couple more ingredients.

If baths aren’t your child’s favorite, you can also try spraying magnesium oil on their abdomen or their feet (dilute with jojoba oil if needed), or magnesium lotion if baths aren’t your child’s thing. I have had great success with this magnesium lotion for bedtime too.

3. Foods Rich in Tryptophan: Tryptophan is an amino acid that helps the body produce serotonin and melatonin naturally. Try offering tryptophan-rich foods at dinner or as part of a calming bedtime snack. Some great options include:

• Bananas
• Turkey
• Oats
• Pumpkin seeds
• Nut butter (on toast, apple slices, or by the spoonful!)

Just remember to keep it light — a big meal right before bed can disrupt sleep.

4. Dim the Lights + Limit Screen Time: Light is one of the biggest signals our bodies use to regulate melatonin production. Bright lights (especially blue light from screens) can block natural melatonin production. About 60–90 minutes before bed, dim the lights in your home and turn off screens to help your child’s body begin producing its own melatonin naturally. While this post talks more about lighting in the nursery, I am a big believer in soft lighting for our children’s bedrooms too.

4. Warm Milk with Sleepy-Time Spices: A classic for a reason — warm milk has long been a trusted bedtime remedy. Milk contains tryptophan (the amino acid that helps the body produce melatonin), and the warmth itself is soothing to the nervous system. You can boost the sleepy-time benefits by adding:

• A pinch of turmeric (anti-inflammatory + grounding)
• A sprinkle of nutmeg (a natural sedative in small amounts)
• A dash of cinnamon for flavor and warmth
• Optional: a teaspoon of raw honey (for kids over 1), a scoop of collagen, or a dash of magnesium powder if your child tolerates it well

Just warm the milk gently and whisk in the extras — no need to boil. This golden bedtime milk can be a cozy, nourishing ritual that your child looks forward to.

5. Calming Bedtime Routine (Consistency is Key): This might not be a supplement or superfood, but honestly, a consistent and predictable bedtime routine is one of the most powerful sleep supports. Kids thrive on rhythm and repetition. A simple routine — like bath, books, snuggles, and lights out — helps their nervous system recognize it’s time to wind down.

6. Herbal Support (Use Cautiously + With Guidance): Some parents find gentle herbal support helpful, like organic chamomile tea, lemon balm, or catnip tea (yes, catnip is calming for humans!). These should be used in small amounts and ideally under the guidance of an herbalist or healthcare provider, especially with young children.

7. Sleep Sprays: Whether these are a bit placebo or not, they might help your child feel better prepared to fall asleep. I have been using this Deep Sleep Spray (use code GN20) on occasion and I think it helps with my kids’ mindset about going to sleep.

💛 Every Child is Different

Remember that what works wonders for one might not work for another. The goal is to support their body’s own sleep rhythms, not to force sleep with something stronger than they need. These gentle melatonin alternatives can help nudge their little bodies into rest without creating dependency or interfering with development.
