As an expert in child and infant sleep problems, I’m well aware of the challenges parents encounter in their quest to ensure their children get adequate rest. The whole family can suffer from sleep deprivation, making the search for a remedy an urgent matter. The use of melatonin for kids as a sleep aid has skyrocketed recently. Despite parents’ desire for a quick solution, I must stress that relying on a melatonin supplement is not the most effective approach to address children’s sleep issues. This article will delve into the reasons, supported by scientific evidence and my own expertise, and suggest alternative methods to improve children’s sleep.

The Rise of Melatonin Use Among Children

Melatonin, a hormone that the brain naturally secretes to manage the circadian rhythm or body clock, is subject to different regulations worldwide. While it’s often a prescription-only drug for individuals under 55 in many countries, in the United States, melatonin is readily accessible over the counter as a dietary supplement, with formulations like child-friendly gummies. This availability has led to a surge in melatonin dosage and use among children, raising questions about appropriate melatonin dose for kids.

Research published in JAMA Pediatrics indicates that nearly one in five school-aged children and preteens now take melatonin for sleep, and melatonin for toddlers is not uncommon, with some parents administering it to preschoolers. A survey of 1,000 parents revealed that 18.5% of children ages 5 to 9, 19.4% of preteens ages 10 to 13, and 6% of preschoolers ages 1 to 4 had taken melatonin in the past month. These figures are alarming, especially given the scant research on the long-term effects and safety of how many mg of melatonin for kids is appropriate, as well as the potential for preschooler sleep issues.

Lack of Regulation and Uncertain Safety

A major concern with melatonin supplements for kids is the absence of strict regulation. Dietary supplements like melatonin are not subject to the same stringent testing and oversight by the FDA as prescription medications. Consequently, the melatonin dosage, purity, and components can differ widely across brands, making it difficult to ensure consistent quality and safety.

An analysis of melatonin gummy products uncovered that 22 out of 25 products had melatonin levels that did not match the label. Some contained more than triple the stated amount, while others lacked melatonin entirely. Furthermore, certain melatonin supplements were found to include other substances, such as serotonin, which could be harmful. This inconsistency and lack of transparency raise significant concerns about the side effects of melatonin in kids and question the reliability of these supplements for long-term use.

Potential Risks and Side Effects

Although melatonin is generally deemed safe for short-term use in adults, the question of ‘is melatonin safe for kids’ remains, particularly for long-term consumption. The research on the prolonged use of melatonin in children is scarce, and the limited studies available have produced mixed findings.

Common side effects of melatonin in kids include irritability, headaches, and drowsiness. In some instances, melatonin can worsen sleep disturbances or cause negative reactions. Reports have surfaced of night terrors, nausea, stomach pain, and heightened aggression in children taking melatonin supplements. These potential risks underscore the need for careful consideration and informed choices when pondering melatonin for children’s sleep issues.

Dangers of Unregulated Online Purchases

One alarming trend is the increasing availability of melatonin 6mg supplements for kids online in Australia. Parents can easily purchase these melatonin Australia products without a prescription or proper medical guidance. However, buying 6mg melatonin supplements online poses significant risks due to the lack of regulation and quality control.

The Therapeutic Goods Administration (TGA) in Australia warns against purchasing melatonin online, as these products may not meet manufacturing quality standards and may contain undisclosed harmful ingredients. A Canadian study found that over-the-counter melatonin for toddlers sold online had inconsistent dosages, with some containing significantly more or less melatonin than stated on the label. This lack of quality control and variation in product composition further emphasizes the potential dangers of unregulated melatonin Australia supplements purchased online.

Understanding the Underlying Issues

While the availability of melatonin supplements may seem like an attractive solution for pediatric sleep disorders, it is essential to address the underlying issues rather than relying solely on medication. Many sleep problems in children are behavioural in nature and can be improved with appropriate pediatric sleep medicine practices, including a calming bedtime routine and behavioural interventions.

As a sleep expert, I recommend that parents explore alternative strategies to promote healthy sleep habits in their children, following pediatric sleep guidelines. These strategies not only provide long-term benefits but also empower parents with tools to address sleep issues effectively.

Alternative Strategies for Better Sleep

  1. Establish a Consistent Bedtime Routine: Creating a predictable routine before bedtime helps signal to the body that it’s time to sleep. Include calming activities such as reading a book or taking a warm bath.
  2. Create a Sleep-Friendly Environment: Ensure the bedroom is conducive to sleep by keeping it dark, quiet, and at a comfortable temperature. Consider using white noise machines or blackout curtains to minimise disruptions.
  3. Limit Screen Time Before Bed: The blue light emitted by electronic devices can interfere with the production of melatonin. Establish a screen-free period before bedtime to allow the body to wind down naturally.
  4. Encourage Physical Activity: Regular exercise during the day can help promote better sleep at night. Engage children in age-appropriate physical activities to expend energy and support healthy sleep patterns.
  5. Promote Relaxation Techniques: Teach children relaxation techniques such as deep breathing exercises or gentle stretching to help them unwind and prepare for sleep.
  6. Seek Professional Help if Needed: If sleep problems persist despite implementing these strategies, consider consulting a pediatric sleep specialist or sleep coach. They can provide personalized guidance and support tailored to your child’s specific needs.


While melatonin supplements may seem like a quick fix for children’s sleep problems, they come with potential risks and uncertainties. The lack of regulation, inconsistent dosages, and unknown long-term effects make melatonin as a sleep aid an unreliable solution for children’s sleep issues. Instead, I encourage parents to explore alternative strategies that address the underlying causes of sleep problems and promote healthy sleep habits, such as implementing a calming bedtime routine. By creating a sleep-friendly environment and seeking professional help when needed, parents can help their children achieve restful and rejuvenating sleep without relying on melatonin supplements.

Remember, as parents, we are not alone in this journey. Together, we can support our children’s sleep health and well-being, providing them with the best foundation for a bright and energized future.
