Sleep is an important part of a child’s health and development, yet pediatric sleep disorders often go unnoticed or misunderstood. Identifying and addressing these issues early can prevent long-term consequences and improve a child’s quality of life.
This guide explores common pediatric sleep disorders, their symptoms, and effective treatment options to help children achieve the restorative sleep they need.
Sleep is Important for Children
Sleep is key to children’s growth, development, and overall health. It’s the foundation for physical health, emotional stability, and cognitive performance so it’s one of the most important things in their daily lives.
Sleep and Development
During sleep, children’s bodies do important work that helps with growth and repair. Growth hormones are released mainly during deep sleep, and physical development. Sleep helps repair tissues, strengthen the immune system, and regulate metabolism.
Beyond physical benefits, sleep is important for brain development. It helps with memory consolidation, problem-solving, and emotional regulation – skills for school and social life.
Sleep Duration by Age
The amount of sleep children need varies by age. According to sleep experts:
- Infants (4-12 months): 12–16 hours (including naps).
- Toddlers (1-2 years): 11–14 hours (including naps).
- Preschoolers (3-5 years): 10–13 hours (including naps).
- School-aged children (6-12 years): 9–12 hours.
- Teenagers (13-18 years): 8–10 hours.
Sleep Deprivation Consequences
When children don’t get enough sleep the consequences can be far-reaching and serious. Sleep deprivation can lead to:
- Academic struggles: Sleep is key to focus, memory, and learning. Sleep-deprived children will struggle to retain information and stay engaged in school.
- Behavioral issues: Lack of sleep leads to irritability, mood swings, and hyperactivity making it harder for children to regulate emotions and behavior.
- Weakened Immune System: Not enough sleep weakens the immune system leaving children more prone to illness.
- Long-term health risks: Chronic sleep deprivation is linked to obesity, diabetes, and cardiovascular disease even at a young age.
Getting children to get enough good sleep helps them thrive and protects their long-term health. Parents have a big role to play in recognizing sleep issues and setting sleep routines that support their child’s well-being.
Common Pediatric Sleep Disorders
Sleep disorders in children are more common than many parents think and can significantly impact a child’s health and daily functioning. Identifying these issues early can help address them effectively.
Insomnia
Insomnia in children is characterized by difficulty falling asleep, staying asleep, or waking up too early and feeling unrested. Common causes include stress or anxiety related to school, social challenges, or family changes. Poor sleep hygiene—such as irregular bedtimes or excessive screen time before sleep—can also contribute to insomnia. If left untreated, insomnia may lead to daytime fatigue, mood changes, and academic difficulties.
Sleep Apnea
Sleep apnea is when a child’s breathing is repeatedly interrupted during sleep, often due to obstructed airways. Symptoms include loud snoring, gasping for air, mouth breathing, and restless sleep.
Unlike adult sleep apnea, which is often linked to obesity, pediatric sleep apnea can be caused by enlarged tonsils or adenoids. Untreated sleep apnea may lead to behavioral problems, learning difficulties, and even heart issues over time.
Restless Leg Syndrome (RLS)
RLS in children causes an irresistible urge to move their legs, which makes trying to fall asleep extremely difficult and uncomfortable. These symptoms typically worsen in the evening, making it hard for children to fall asleep.
While the exact cause is unknown, RLS can be associated with low iron levels or certain genetic factors. Children with RLS may experience disrupted sleep, resulting in irritability and concentration problems during the day.
Night Terrors and Sleepwalking
These parasomnias occur during deep sleep and are more common in younger children. Night terrors involve episodes of intense fear, screaming, and thrashing, often with no memory of the event upon waking.
Sleepwalking, on the other hand, involves walking or performing other activities while still asleep. Both conditions are typically harmless but can be alarming for parents. They tend to decrease in frequency as children grow older.
Circadian Rhythm Disorders
Circadian rhythm disorders, such as delayed sleep phase disorder, are often seen in teenagers. These conditions disrupt the body’s internal clock, causing difficulty falling asleep at conventional times and waking up early for school. Teens with this disorder may experience chronic sleep deprivation, affecting their academic performance and emotional well-being.
Behavioral Sleep Disorders
Behavioral sleep disorders are common in children with neurodevelopmental conditions such as ADHD or sensory processing disorders. These issues may manifest as difficulty settling down for sleep, resistance to bedtime, or frequent nighttime awakenings. Addressing the underlying condition through therapy and tailored strategies can help improve sleep patterns.
Warning Signs and Symptoms
How do you know if your child has a sleep problem? Sleep disorders can be subtle or obvious and often exhibit a combination of behavioral, physical, and sleep characteristics. Being aware of the warning signs and symptoms is critical to getting the help your child may need.
Behavioral Symptoms
Children with sleep disorders often exhibit the following behavioral symptoms.
- Excess energy: Lost sleep can cause kids to be extremely “hyper” or bounce off the wall. They may mimic ADHD behavior.
- Mood swings: We all drag around when we don’t get enough rest, and kids are no exception. They may become short or crankier than usual.
- Daydreaming: Fatigued kids have trouble focusing and concentrating. They may have difficulty completing homework or paying attention at school or during daily activities.
Physical Symptoms
Sleep disorders can also present through physical signs, including:
- Snoring: Snoring is normal on occasion, but heavy snoring can indicate the presence of sleep apnea.
- Headaches and/or Earaches: Muscle tension and misaligned jaw structures can cause headaches and earaches.
- Tooth Grinding: Stressed jaws promote teeth grinding.
- Facial Pain: Pain in the jaw, face, and head can be symptoms of a sleep disorder.
- Mouth breathing: Primary mouth breathing, especially at night, can indicate enlarged tonsils and or other airway restrictions.
- Nighttime Enuresis: Older children who wet the bed at night may have a sleep-related issue or underlying sleep disorder.
Sleep Patterns
Unusual sleep habits or difficulties can also signal underlying issues.
- Waking up at night: Waking up multiple times during the night can be a symptom of sleep disorders like restless leg syndrome or sleep apnea.
- Resisting sleep or bedtime: Your child may resist going to bed or display aggressive or clingy behavior at bedtime.
- Night terrors: Instead of a nightmare, your child may experience night terrors, which are often a result of excessive stress and fatigue.
- Grogginess in the morning: If your child is hard to wake up in the morning and sleeps late, it may be a sign that they are not relaxing and entering into restful stages of sleep at night.
- Sleeping during day events: Napping every day or falling asleep during activities you do together, such as dinner or movies, is sleeping away 1/3 of your child’s waking day. While younger kids need regular naps, excessive daytime sleeping can be a sign of a sleep disorder.
Diagnosing Pediatric Sleep Disorders
Diagnosing sleep disorders in children often requires collaboration between parents, pediatricians, and sleep specialists. These professionals play a critical role in identifying the underlying causes of sleep issues and recommending effective treatments.
The Role of Sleep Specialists and Pediatricians
Pediatricians are often the first point of contact when parents notice sleep-related concerns. They can evaluate symptoms, rule out common medical conditions, and determine whether a referral to a sleep specialist is necessary. Sleep specialists bring advanced expertise in diagnosing and managing sleep disorders, using specialized tools and techniques to uncover the root of the problem.
Tools Used in Diagnosis
- Sleep Studies (Polysomnography): A sleep study conducted by a professional sleep specialist is a gold standard for diagnosing many pediatric sleep disorders, including sleep apnea and restless leg syndrome. Conducted in a sleep lab or at home, polysomnography monitors brain activity, breathing patterns, heart rate, oxygen levels, and muscle movements while the child sleeps. This comprehensive data helps specialists pinpoint specific issues and guide treatment.
- Sleep Diaries or Actigraphy: Parents are often asked to maintain a sleep diary, recording their child’s bedtime, wake time, and any disturbances during the night. Alternatively, actigraphy involves the use of a wearable device that tracks movement and sleep patterns over several days or weeks, providing objective data about the child’s sleep-wake cycles.
- Parent-Reported Questionnaires or Symptom Tracking: Questionnaires and surveys can help identify behavioral and physical symptoms that might indicate a sleep disorder. These tools often assess the frequency and severity of symptoms such as snoring, daytime fatigue, or difficulty falling asleep.
When Parents Should Seek Medical Advice
Parents should consult a healthcare professional if they notice persistent sleep issues, such as:
- Loud snoring or gasping for air during sleep.
- Frequent nighttime awakenings or difficulty falling asleep.
- Daytime fatigue, irritability, or hyperactivity that interferes with daily activities.
- Unusual behaviors during sleep, such as night terrors or sleepwalking.
Treatment Options
Effective treatment for pediatric sleep disorders often involves a combination of lifestyle changes, behavioral strategies, and medical interventions.
Lifestyle Modifications
A calming and predictable bedtime routine is essential for helping your child wind down and prepare for a good night’s sleep. This is the time to engage your child in gentle activities like reading a book together or a warm bath. Consistency is key, so set the bedtime routine and stick to it from week to week.
Establish a caffeine and sugar-free diet for your child. Both substances are stimulants and can interfere with the body’s ability to relax and fall asleep. Caffeine is obvious, but sugar is just as detrimental. It’s easy to forget that many of our kids’ favorite foods and beverages, like flavored yogurt, granola, and tea, contain sugar.
Avoid exposure to screens (digital devices, TVs, and computers) at least an hour before bedtime. They emit a blue light that delays the production of melatonin, the sleep hormone. This makes it increasingly difficult for your child to fall asleep and can set off a chain reaction of insomnia.
Behavioral Strategies
Behavioral therapies are the most effective way to treat pediatric sleep disorders. A child sleep version of Cognitive Behavioral Therapy for Insomnia (CBT-I) helps kids identify and change bad dreams and wake-up fantasies, and it teaches them how to fall asleep and stay asleep.
Another important component is to add a relaxation piece to your bedtime routine. Deep breathing, progressive muscle relaxation, and mindfulness are all great techniques to calm your child’s restless mind and body.
Medical Interventions
If your child’s sleep apnea is caused by obstructive sleep apnea, your doctor might recommend oral appliances, such as a CPAP (continuous positive airway pressure) therapy. The child would use a CPAP machine, which hangs from the bed or is carried in a backpack, to breathe in pressurized air through a mask that covers the nose and mouth. The pressure opens up the pathways in the throat, allowing your child to sleep safely through the night. If your child has restless leg syndrome, narcolepsy, or another underlying medical condition, your doctor may prescribe medications.
However, medications are not lightly prescribed for children and are typically reserved for severe cases. They’re often used in conjunction with other therapies and monitored closely to minimize side effects. Medical interventions are always tailored to the child and are dependent on the severity of the sleep problem.
Addressing the Underlying Cause of Sleep Disturbances
In many cases, your child’s sleep disturbance is related to an underlying issue that can be addressed.
If your child has allergies, managing the symptoms with immunotherapy or medications can help your child sleep more comfortably. If your child has anxiety, addressing the underlying fear or stress can alleviate racing thoughts and anxiety attacks.
If your child has ADHD, adjusting the timing of medications or adding a bedtime behavior modification program can help your child sleep more soundly. Primary care physicians and other caregivers can help you address the underlying issue and develop a comprehensive plan to address sleep disruptions and promote healthier sleep habits.
