Is it normal for my toddler to snore?

Occasional snoring during a cold or upper respiratory infection is common and usually harmless. Regular, loud snoring on most nights is not normal in children at any age and should be assessed by a paediatrician or ENT specialist. It may indicate enlarged tonsils and adenoids or obstructive sleep apnea, both of which are treatable and can significantly affect behaviour and development if left unaddressed.

Should I wake my child during a night terror?

Generally no. Attempting to fully wake a child from a night terror is usually unsuccessful, can intensify distress, and may extend the episode. The best approach is to ensure the child is safe (not near furniture or stairs), speak calmly but without demanding response, and wait for the episode to resolve on its own — which typically takes 1–5 minutes. The child will often settle back to sleep without any memory of the event.

Can ADHD medication cause sleep problems?

Yes. Stimulant medications used for ADHD — methylphenidate (Ritalin) and amphetamine-based medications — can delay sleep onset in children, particularly when taken in the afternoon. Evening dosing should be minimised where possible. Discuss with your prescribing paediatrician if sleep initiation worsens after starting ADHD medication. Sometimes adjusting the timing or formulation of medication resolves the sleep issue without reducing ADHD control.

How long do sleep terrors last in children?

Individual episodes typically last 1–15 minutes. As a condition, sleep terrors are most common between ages 3–7 and in most children resolve spontaneously during late childhood or early adolescence without any specific treatment. Sleep deprivation and irregular schedules both trigger episodes, so addressing these factors can reduce their frequency. In a small minority of cases, parasomnias persist into adulthood and may warrant sleep study evaluation.

Sleep Disorders in Children: Recognition and Treatment

Sleep is not optional for children — it is essential infrastructure for growth, learning, and emotional development. Yet sleep disorders in children are both more common than many parents realise and frequently unrecognised, because the way poor sleep manifests in children looks very different from what adults expect. Understanding these differences is key to getting the right help.

Why Children's Sleep Disorders Look Different

Adults who are sleep-deprived become sluggish, drowsy, and slow. Children who are sleep-deprived often become hyperactive, irritable, impulsive, and emotionally dysregulated. The immature nervous system responds to sleep deprivation with increased activation rather than sedation — which means that a chronically sleep-deprived child may look like they have too much energy, not too little.

This fundamental difference in presentation means that paediatric sleep disorders are frequently misattributed to — or genuinely complicated by — ADHD, behavioural problems, learning difficulties, or emotional disorders. Multiple studies have found that a significant proportion of children diagnosed with ADHD have an unrecognised sleep disorder contributing to or causing their symptoms. In some cases, treating the sleep disorder substantially reduces or resolves the behavioural presentations.

How Much Sleep Do Children Need?

Sleep needs are substantially greater in children than adults and vary considerably by age. The American Academy of Sleep Medicine guidelines:

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-age children (6–12 years): 9–12 hours
Teenagers (13–18 years): 8–10 hours

These are not aspirational targets — they represent the minimum range for optimal neurodevelopmental outcomes. Children chronically sleeping below these ranges show measurable effects on learning, behaviour, emotional regulation, and growth.

Behavioural Insomnia of Childhood

The most common sleep disorder in infants and young children. It arises in two main patterns:

Sleep-onset association disorder: The child has learned to fall asleep only under specific conditions that require parental involvement — being rocked, fed, held, or having a parent in the room. When the child wakes naturally during the night (which is normal for everyone), they cannot return to sleep without recreating those conditions, triggering repeated night-time calling or crying.

Limit-setting disorder: The child resists going to bed, employs delaying strategies (requests for water, another story, bathroom trips), and does not settle without extensive parental attention. Often seen in older toddlers and preschool-age children.

Both forms respond well to behavioural sleep interventions: establishing consistent, age-appropriate routines; gradually reducing parental involvement in sleep onset (extinction or graduated extinction/"Ferber" methods); and consistent enforcement of reasonable limits. These approaches are evidence-based and do not cause psychological harm when implemented thoughtfully.

Paediatric Obstructive Sleep Apnea

Paediatric OSA differs importantly from adult OSA in its primary cause. While adult OSA is most commonly driven by obesity and muscle atonia, paediatric OSA is most commonly caused by enlarged tonsils and adenoids (adenotonsillar hypertrophy) that physically obstruct the upper airway during sleep. This makes paediatric OSA both more anatomically clear-cut and — in most cases — surgically curable.

Symptoms of paediatric OSA include:

Loud, habitual snoring (not occasional snoring during a cold, but regular snoring most nights)
Witnessed breathing pauses during sleep, or gasping and choking arousals
Restless, disturbed sleep with unusual sleeping positions (hyperextended neck, sleeping with head elevated on multiple pillows)
Mouth breathing during sleep
Night sweats
Bedwetting (secondary nocturnal enuresis) in a child who was previously dry — an often overlooked sign
Morning headaches
Daytime hyperactivity, attention problems, irritability, or learning difficulties

Diagnosis requires a sleep study — either a home test or in-lab polysomnography depending on the clinical picture. The primary treatment for adenotonsillar-driven paediatric OSA is adenotonsillectomy (surgical removal of tonsils and adenoids), which resolves OSA completely in approximately 80% of non-obese children. For obese children with OSA, CPAP and weight management are also typically required.

NREM Parasomnias: Night Terrors and Sleepwalking

Children spend a greater proportion of sleep in slow-wave (deep) sleep than adults — and NREM parasomnias arise from deep sleep. This is why sleepwalking and sleep terrors are far more common in children than in adults.

Sleep terrors: Episodes of partial arousal from deep sleep in which the child sits up or stands, screaming inconsolably with eyes open but appearing terrified and unaware. Heart rate and breathing are elevated. The child does not respond to comfort and has no memory of the event the following morning. Episodes typically last 1–5 minutes. Peak age is 3–7 years. Often frightening for parents but not harmful to the child.

Sleepwalking: Also arising from deep sleep — the child gets out of bed and performs complex behaviours (walking around, going to the kitchen, attempting to leave the house) while asleep and unresponsive. Eyes may be open but glassy. The child is not conscious and has no memory of the episode.

Management of NREM parasomnias: Ensure physical safety (stair gates, locked exterior doors, clear bedroom floor), avoid waking the child during an episode (this rarely succeeds and can cause agitation), address sleep deprivation and irregular schedules (which trigger episodes), and reassure parents that most children fully outgrow these conditions by adolescence.

Restless Legs Syndrome in Children

RLS can occur in children and is more common than previously recognised. The diagnostic challenge is that young children often describe the symptoms differently from adults — "ouch in my legs," "my legs feel like they need to run," "my legs feel silly." The diagnosis requires recognising these equivalent descriptions and applying age-appropriate diagnostic criteria.

Paediatric RLS is associated with iron deficiency (ferritin below 50 mcg/L), ADHD (which co-occurs at elevated rates and shares neurobiological overlap), and a family history of RLS. Iron supplementation to correct deficiency is often the first and most effective treatment.

Circadian Rhythm Disorders in Adolescents

Adolescence is associated with a biological shift toward later chronotype — the circadian clock shifts later during puberty, meaning teenagers genuinely cannot fall asleep as early as they could as children and cannot wake early without significant difficulty. This biological shift collides with early school start times in many countries, creating a form of chronic social jet lag that affects a large proportion of adolescents.

At the more severe end, this can be a diagnosable Delayed Sleep-Wake Phase Disorder, where the inability to fall asleep before 2–4am is a genuine neurobiological condition, not a lifestyle choice. Advocacy for later school start times — now supported by the American Academy of Pediatrics — reflects this biological reality.

When to Speak With a Doctor

If your child snores loudly most nights, has witnessed breathing pauses during sleep, wets the bed after previously being dry, or is having significant school or behavioural difficulties that began alongside sleep changes, speak to your paediatrician. Paediatric sleep disorders are common, frequently unrecognised, and often highly treatable — early identification can make a substantial difference to a child's development and quality of life.
