Sleep Disorders in Children in BC: Signs, Diagnosis, and Where to Get Help
Last Updated: May 30, 2026
Sleep disorders in children are more common than many parents realize, and they can have significant effects on a child's behaviour, learning, and development. In British Columbia, pediatric sleep disorders are assessed and managed through a combination of family doctors, pediatricians, and specialized pediatric sleep programs. This guide explains the most common sleep disorders in BC children, how they are diagnosed, and how to access care.
How Much Sleep Do Children Need?
Sleep requirements vary by age. The Canadian Paediatric Society recommends:
| Age Group | Recommended Sleep |
|---|---|
| Infants (4 to 12 months) | 12 to 16 hours (including naps) |
| Toddlers (1 to 2 years) | 11 to 14 hours (including naps) |
| Preschoolers (3 to 5 years) | 10 to 13 hours (including naps) |
| School-age (6 to 12 years) | 9 to 12 hours |
| Teenagers (13 to 18 years) | 8 to 10 hours |
Consistently sleeping less than recommended is associated with increased risk of obesity, mental health problems, behavioural difficulties, and academic underperformance.
Common Sleep Disorders in BC Children
Pediatric obstructive sleep apnea (OSA): The most common sleep-related breathing disorder in children. Caused by obstruction of the upper airway during sleep, most commonly due to enlarged tonsils and adenoids. Affects approximately 1 to 5 percent of children. Signs include loud snoring, witnessed breathing pauses, restless sleep, mouth breathing, and daytime behavioural problems. Treatment often involves tonsillectomy and adenoidectomy (T&A), which resolves sleep apnea in 70 to 90 percent of otherwise healthy children.
Behavioral insomnia of childhood: Difficulty falling asleep or staying asleep due to learned sleep associations or limit-setting problems. Very common in toddlers and preschoolers. Responds well to behavioural interventions (graduated extinction, bedtime fading, positive routines).
Restless legs syndrome (RLS) and periodic limb movement disorder (PLMD): RLS causes uncomfortable sensations in the legs at rest, typically worse in the evening. PLMD involves repetitive limb movements during sleep. Both can disrupt sleep and cause daytime symptoms. RLS in children is associated with iron deficiency - checking ferritin levels is an important first step.
Parasomnias: Sleep behaviours including sleepwalking, sleep terrors, confusional arousals, and nightmares. Most parasomnias are benign and resolve with age. Sleep terrors and sleepwalking are most common in children aged 3 to 8 years. Safety precautions (stair gates, door alarms) are important for sleepwalking children.
Delayed sleep phase syndrome (DSPS): Common in teenagers, DSPS involves a shift in the circadian rhythm such that the teenager cannot fall asleep until late at night (1 to 3 AM) and has difficulty waking in the morning. This is a biological circadian rhythm disorder, not simply a behavioural problem. Treatment includes light therapy, melatonin, and sleep schedule adjustment.
Narcolepsy: A chronic neurological disorder causing excessive daytime sleepiness, sudden muscle weakness triggered by emotion (cataplexy), sleep paralysis, and hypnagogic hallucinations. Rare but can present in childhood and adolescence. Requires specialist diagnosis and management.
How Pediatric Sleep Disorders Are Diagnosed in BC
Step 1: Family doctor assessment. Your family doctor or pediatrician is the starting point. They will assess your child's sleep history, symptoms, and development. For suspected sleep apnea, they may refer to an ENT (ear, nose, and throat) specialist or a pediatric sleep program.
Step 2: Specialist referral. Depending on the suspected diagnosis, your child may be referred to:
- A pediatric ENT for assessment of tonsil and adenoid size (for suspected sleep apnea)
- A pediatric sleep program for polysomnography (sleep study)
- A pediatric neurologist for suspected narcolepsy or complex parasomnias
- A child psychologist for behavioral insomnia
Step 3: Pediatric sleep study (polysomnography). If a sleep study is needed, BC Children's Hospital in Vancouver has a dedicated pediatric sleep program. Wait times for pediatric sleep studies at BC Children's Hospital are typically 3 to 9 months for non-urgent referrals. Some private sleep clinics offer pediatric home sleep testing for appropriate cases.
BC Children's Hospital Sleep Program
BC Children's Hospital (bcchildrens.ca) operates one of the few dedicated pediatric sleep programs in BC. The program assesses and treats children with complex sleep disorders including sleep apnea, narcolepsy, and parasomnias.
How to access BC Children's Hospital Sleep Program:
- Referral from a family doctor or pediatrician is required
- The program serves children from across BC
- Wait times vary by urgency and diagnosis
Other pediatric sleep resources in BC:
- Your child's family doctor or pediatrician for initial assessment and management of common sleep problems
- BC Children's Hospital general pediatrics for complex cases
- Child and Youth Mental Health (CYMH) programs through BC health authorities for behavioral sleep problems with mental health components
When to See a Doctor About Your Child's Sleep
See your family doctor or pediatrician if your child:
- Snores loudly or has witnessed breathing pauses during sleep
- Has excessive daytime sleepiness despite adequate sleep time
- Has significant behavioral or learning problems that may be related to poor sleep
- Has restless legs or frequent leg movements during sleep
- Has frequent parasomnias (sleepwalking, sleep terrors) that are disruptive or dangerous
- Has difficulty falling asleep or staying asleep that is significantly affecting family functioning
Frequently Asked Questions
My child snores - should I be concerned? Occasional light snoring is common in children and usually not a concern. Loud, habitual snoring (most nights) with witnessed breathing pauses, restless sleep, or daytime behavioural problems warrants assessment by your family doctor or pediatrician. This may indicate pediatric sleep apnea.
What is the treatment for pediatric sleep apnea in BC? For most children, enlarged tonsils and adenoids are the cause. Tonsillectomy and adenoidectomy (T&A) resolves sleep apnea in 70 to 90 percent of otherwise healthy children. For children who are not candidates for surgery, CPAP therapy is used. Your child's ENT or sleep specialist will recommend the appropriate treatment.
Is melatonin safe for children? Melatonin is commonly used for children with sleep onset difficulties, particularly those with autism spectrum disorder or ADHD. Short-term use appears safe. Long-term safety data in children is limited. Consult your child's doctor before starting melatonin. Health Canada recommends melatonin for children only under medical supervision.
How do I help my toddler sleep through the night? Behavioral insomnia of childhood (difficulty settling or night waking) is very common in toddlers and responds well to behavioral interventions. Consistent bedtime routines, graduated extinction (controlled crying), and positive reinforcement are evidence-based approaches. Ask your family doctor or public health nurse for guidance.
What is delayed sleep phase syndrome in teenagers? Delayed sleep phase syndrome (DSPS) is a circadian rhythm disorder common in teenagers where the biological clock is shifted later, making it difficult to fall asleep before 1 to 3 AM and difficult to wake in the morning. It is a biological condition, not simply a behavioural problem. Treatment includes morning light therapy, low-dose melatonin in the early evening, and gradual sleep schedule adjustment. Ask your family doctor for a referral if you suspect DSPS.
