Baby Melatonin: The Facts From A Sleep Expert

You will often hear me talk about melatonin when children are preparing to go to sleep, but what actually is melatonin and why is it so important? And what has baby melatonin got to do with it all?

What Is Melatonin?

Melatonin is a hormone that regulates the sleep-wake cycle in humans. It is produced by the pineal gland in response to darkness and is responsible for our sleep patterns for how and when we sleep.

How Does Melatonin Work?

Melatonin is released by the pineal gland when our brains recognise that our surroundings are getting darker. This triggers a chain reaction in your body to start winding itself down for rest. Because of this, melatonin has often been referred to as a “sleep hormone.”

While melatonin production isn’t essential for sleeping, you will sleep better when you have the highest levels of melatonin in your body.

The reverse happens when our brains recognise our surroundings are getting or remaining light. Exposure to bright light (from screens to house lights) suppresses the release of melatonin which can lead to difficulties falling asleep and staying asleep.

NOTE: You have low melatonin levels during the daylight hours and peak levels of melatonin during the nighttime. Therefore, the longer the night, the longer your pineal gland secretes melatonin… Which is why people living in the Northern Hemisphere struggle to wake up in the depths of winter!

Do Babies Produce Melatonin?

Not at first.

In babies, the production of melatonin is not fully developed until they are about 3-4 months old and this is why newborns sleep for shorter periods and wake up frequently.

Once baby’s hypothalamus develops more and starts to respond to the difference between light and dark, the biological internal clock that regulates the sleep-wake cycle (also known as the circadian rhythm) begins to become established.

Baby Melatonin Supplements And Their Types

Melatonin supplements are available over-the-counter and are commonly used to treat sleep disorders in adults.

However, you need to be very careful when considering giving melatonin supplements to your baby and that is why their use in babies is not recommended without consulting a pediatrician.

There is limited research on the safety and effectiveness of melatonin supplements in babies, and there is a real risk that these supplements may have adverse effects on your little one development.

There are different types of melatonin supplements available, including:

liquid drops,
chewable tablets,
and gummies.

As with all drugs or supplement taking, it is important to follow the dosage instructions carefully and not exceed the recommended amount.

NOTE: It is also important to ensure that the supplement does not contain any additional ingredients that could be harmful to your child.

Use Of Melatonin In Babies

If your baby is having sleep difficulties such as trouble falling asleep or staying asleep, you may be considering using melatonin.

While melatonin is generally safe for adults and children with sleep disorders when taken as prescribed by a doctor, there isn’t enough evidence on infant safety.

I cannot say it enough…

Before giving melatonin to your baby, please discuss the potential risks and benefits with your child’s paediatrician.

Melatonin Dosage For Babies

Because of the lack of research and medical evidence about giving melatonin to babies, there is no official recommended dosage for this age group and giving your baby too much can be dangerous.

The American Academy of Pediatrics (AAP) recommends against giving melatonin to healthy children. If you feel your baby has a sleep disorder, the AAP advises that you speak with your paediatrician to determine if melatonin is appropriate and what dosage to use.

Safety and Side Effects of Melatonin Supplements

When considering giving your baby melatonin supplements, it is important to understand the potential adverse effects and safety concerns associated with their use.

As there have been no official reports on baby melatonin, the following is a list of potential adverse effects of taking melatonin supplements in adults and children.

Therefore they should definitely be noted if you are considering giving them to your baby:

Headaches
Drowsiness
Nausea
Dizziness
Irritability
Mood changes
Restless leg
Increased urination
Daytime drowsiness

Long-Term Effects Of Melatonin On Babies

The long-term effects of melatonin in babies and children are not well understood. Melatonin can affect hormonal development, which is particularly important in babies and young children.

NOTE: Pediatric melatonin ingestions have increased in recent years, and calls to poison control centres for melatonin have also increased. Always keep melatonin out of children’s reach to prevent accidental ingestion.

Improving Sleep Habits in Babies Without Using Melatonin

As a parent, you know that getting your baby to sleep through the night can be a challenge.

However, there are some things you can do to help your little one develop healthy sleep habits without resorting to taking melatonin supplements.

1. Establish A Routine

One of the most important things you can do to help your baby sleep better is to establish a consistent bedtime routine. This should include a quiet lead-up to bedtime, a bath and a bedtime story,

By following the same routine every night at the same time every night, you will help your baby learn when it’s time to sleep.

2. Monitor Behavior

It’s important to pay attention to your baby’s behavior during the day to help them get a better night’s sleep. Make sure they are getting enough physical activity during the day.

Also, limit screen time and electronic devices in the hours before bedtime, as the blue light emitted by these devices interferes with the sleep cycle, making it harder for baby to fall and stay asleep.

3. Get Daytime Sleep Right

Ensuring your baby gets the right amount of sleep in a 24-hour period is essential to establishing a healthy bedtime routine and successful nighttime sleep.

Make sure your little one is getting enough hours of sleep so that they are primed and ready for bedtime when it comes around.

4. Use Sleep Strategies

There are several sleep strategies you can use to help your baby fall asleep and stay asleep.

These include swaddling, using a white noise machine, and having a pacifier.

Sleep associations will vary from baby to baby, so see what your little one prefers and use it to your advantage!

5. Focus On Nutrition

Good nutrition is essential for your baby’s overall health, including their sleep. Make sure your baby is getting enough to eat during the day and try to avoid feeding them right before bed.

Additionally, if you’re still breastfeeding, avoid drinking caffeine, as it gets passed to baby through your breast milk which will interfere with their sleep. If baby is weaning, avoid high-sugar foods before bed.

6. Create A Calm Environment

Creating a calm and relaxing sleep environment can help your baby feel more comfortable and fall asleep faster.

This can include dimming the lights, using a comfortable mattress and bedding, black out blinds and keeping the room at a comfortable temperature between 16-20°C (61-68°F).

7. Avoid Rocking To Sleep

While it may be tempting to rock your baby to sleep, this can create an unhealthy sleep association. Try to always put your baby down drowsy but awake, so they learn to fall asleep on their own.

Age-Appropriate Sleep Schedules

One of the best ways to combat sleep issues in babies and young children is to be well-informed about what their sleep requirements are.

If you want to know what baby’s regular sleep schedule should look like, here are my posts to ensure your little one is getting enough age-appropriate sleep.
