Restless sleep in toddlers can be caused by various factors, including teething, growth spurts, underlying sleep conditions, or even just the excitement of processing new information. Creating a calm and consistent bedtime routine is essential for toddlers' sleep hygiene, and it may be beneficial to limit stimulants and screen time before bed. While some restlessness is normal, if your toddler's sleep is consistently disturbed, it may be worth consulting a healthcare professional to rule out any underlying sleep disorders or iron deficiencies.

What You'll Learn
Teething pain
Teething is a normal yet uncomfortable part of your baby’s growth and development. It is the process that your baby goes through as their teeth break through their gums. Teething can cause pain, drooling, fussiness, and discomfort. The gums around the erupting teeth may be swollen and tender.
The primary teeth (baby teeth) usually start coming in between the ages of 6 and 12 months. The first molars start to come in between 13 and 19 months. All of the baby teeth will gradually come in until they have a full set in place by the age of 2 and a half to 3 years. The last set of baby teeth to come in are the two-year molars, which are the four toddler teeth located in the very back on either side, at the top and bottom.
There are some marketed methods for teething relief that should be avoided, such as teething gels, which are not always regulated for safety or efficacy, and amber teething necklaces and bracelets, which present choking and strangulation hazards.
If your at-home pain management strategies are not helping your toddler’s teething symptoms, you should reach out to your pediatrician or a pediatric dentist. They can help you come up with a better course of action. In the meantime, you can make some simple changes to help improve the quality of your child's sleep. For example, you can stick to a regular nap and nighttime schedule, and avoid stimulants like chocolate, caffeinated drinks, antihistamines, or decongestants. Reducing rough-housing and screen time in the hour before bedtime can also help.

Sleep regression
There are several factors that contribute to sleep regression in 2-year-olds. One of the main reasons is the achievement of developmental milestones, such as learning to walk, talk, and gain independence. The excitement of mastering new skills like climbing, jumping, and running can make it challenging for toddlers to settle down and relax at bedtime. Additionally, the emergence of new teeth, commonly known as teething, can cause discomfort and disturb sleep patterns.
Another factor is the transition in a toddler's environment or routine. Changes such as moving to a new home, starting daycare, or adjusting bedtime routines can disrupt their sleep patterns and trigger sleep regression. These transitions may evoke feelings of anxiety or insecurity, making it more difficult for the child to fall asleep and maintain restful sleep throughout the night. Some toddlers may also experience separation anxiety during this developmental stage.
To manage sleep regression, it is essential to establish a calm and soothing sleep environment. This includes maintaining a dark, quiet, and cool bedroom, and using nightlights or white noise machines to alleviate any fears or anxieties associated with sleeping in the dark. Implementing a consistent bedtime routine or schedule is crucial, as it helps toddlers feel secure and promotes emotional and behavioural regulation. Additionally, creating a predictable nap and wake window routine by following your child's sleep cues is beneficial.
It is also important to be mindful of stimulants such as chocolate, caffeinated drinks, antihistamines, or decongestants, which can contribute to restlessness. Reducing screen time before bedtime and incorporating relaxing activities, such as bedtime sweet talk, can help prepare your child's mind and body for sleep. If sleep issues persist or are accompanied by symptoms like snoring or breathing difficulties, it is recommended to consult a healthcare professional for further guidance.

Lack of physical activity during the day
A toddler's sleep can be affected by a variety of factors, including their daily routine and physical activity levels. If your 2-year-old is a restless sleeper, it could be due to a lack of physical activity during the day.
Ensuring that your toddler is getting enough physical activity during the day can help promote a good night's sleep. Toddlers have abundant energy, and if they don't get a chance to expend it through physical activities, they may have difficulty settling down at night. Encourage active play throughout the day, such as running, jumping, dancing, or playing at the park. This will help tire them out physically and mentally, making it easier for them to fall asleep and improve their overall sleep quality.
Additionally, establishing a consistent bedtime routine is crucial for toddlers. A calming routine before bedtime can help signal to your child that it's time to wind down. Avoid stimulating activities and rough-housing close to bedtime, as this can excite your toddler and make it harder for them to relax. Instead, opt for quieter activities such as reading books, taking a warm bath, or listening to soothing music. This transition period from active play to restful sleep is essential for preparing your toddler's body and mind for a good night's rest.
Another factor to consider is screen time. Reducing screen time before bed is advisable, as the blue light emitted by electronic devices can interfere with your toddler's natural sleep cycle. Instead of screen time, engage in activities that promote interaction and calmness, such as reading a bedtime story or having a gentle conversation about the day's positive events. This can help relax your child's mind and prepare them for sleep.
If your toddler continues to experience restless sleep despite your efforts, it may be worth consulting a healthcare professional. They can provide personalized advice and rule out any underlying issues that may be contributing to your toddler's sleep difficulties.

Iron deficiency
Restless sleep disorder (RSD) is a newly recognised paediatric sleep disorder characterised by frequent body movements during sleep and daytime impairment. The association between RSD and iron deficiency has been well documented, particularly in the pathogenesis of restless legs syndrome (RLS). Iron deficiency is the most common preventable nutritional deficiency globally and a leading cause of anaemia. It is associated with alterations in development and behaviour, especially during infancy and toddlerhood, when there is rapid growth and a high need for iron.
The highest prevalence of iron deficiency anaemia (IDA) in infancy coincides with rapid changes in sleep organisation. Studies have shown that infants with IDA exhibit alterations in sensory pathway functioning and motor activity patterns, with some differences persisting despite timely correction of anaemia with carefully supervised iron therapy. Other studies have found poorer mental, motor, and social-emotional functioning in IDA infants, with differences observed years after iron treatment. Animal studies also show that rodents experiencing early iron deficiency have persisting behavioural differences related to motor function, learning, memory, and emotional responses.
The diagnostic criteria for RLS rely on patients describing an often unpleasant urge to move their legs, which leads to significant sleep disturbance. However, children under five years old frequently have difficulty expressing such symptoms and may instead complain about sleep difficulties, such as insomnia, restless sleep, frequent awakenings, or frequent movements during sleep. These sleep issues can lead to daytime dysfunction, including increased sleepiness, behavioural outbursts, or hyperactivity.
Treatment with oral or intravenous iron supplementation has been highly effective in treating iron deficiency-related sleep disorders. While the official diagnosis of RSD requires three months of restless sleep, it is recommended to consult a healthcare provider as soon as these nighttime disturbances start affecting your child's mood, behaviour, or ability to function during the day. Iron supplements are often prescribed to treat restless sleep disorders, but it is important to speak with a healthcare provider before giving your child any supplements. Additionally, incorporating iron-rich foods like meats and legumes into your child's diet can help increase their iron intake.

Consumption of stimulants
It is important to consider your child's diet and any stimulants they may have consumed if they are experiencing restless sleep. Caffeine, for example, is a well-known stimulant that can affect sleep. While you may not give your child caffeine directly, it can be present in surprising places. Chocolate, for instance, contains a small amount of caffeine, and if consumed close to bedtime, it could impact your child's sleep. Similarly, sugar can act as a stimulant and cause restlessness if consumed in large quantities or too close to bedtime. This includes not just added sugars but also natural sugars found in fruit juices and other sweet snacks.
Another stimulant that can impact sleep is nicotine. If your child has been exposed to secondhand smoke, it could be a factor in their restless sleeping. Even small amounts of nicotine can have an impact on a child's developing nervous system and disrupt their sleep patterns. It is important to create a smoke-free environment for your child, both for their overall health and for a better night's rest.
In addition to these common stimulants, certain medications can also act as stimulants and disrupt sleep. For example, some over-the-counter cold and flu medications contain pseudoephedrine, a stimulant that can cause restlessness and insomnia in children. Always read the labels and consult your pediatrician before giving any medication to your child, and be mindful of the potential side effects on sleep.
While less common, it is worth considering other stimulants your child may have been exposed to. For example, some children may inadvertently consume caffeine-containing energy drinks or even small amounts of illegal stimulant drugs, such as cocaine or methamphetamine, if they are within reach and accidentally ingested. Ensuring a safe and secure environment for your child is crucial, along with educating them about the dangers of such substances as they grow older.
Finally, some children may be more sensitive to natural stimulants such as sunlight and fresh air. While these are generally positive and healthy parts of a child's day, if they are overexposed, it could lead to overstimulation and restless sleep. Ensuring a consistent bedtime routine that includes winding down and preparing the body and mind for sleep can help counteract any overstimulation from the day's activities.
If you suspect that your child's restless sleep is related to stimulant consumption, make necessary dietary adjustments and observe any changes in their sleep patterns. Limiting sugar and caffeine intake, especially close to bedtime, creating a smoke-free environment, and being mindful of medication side effects can all contribute to improving your child's sleep quality. Remember, every child is unique, and it may take some trial and error to identify the specific factors affecting their sleep.
