Every parent deals with sleep battles at some point. The toddler who won’t stay in bed. The school-age kid who resists bedtime like it’s a personal insult. The teenager who seems incapable of waking before noon. Most of these are developmental phases. They’re frustrating, sometimes exhausting, but they pass.

Some sleep problems, though, aren’t phases. They’re disorders — conditions with identifiable causes that won’t resolve on their own and can significantly affect a child’s development, behaviour, and quality of life. Knowing the difference is important, because the interventions for genuine sleep disorders are effective but require proper assessment.

Red Flags That Warrant Investigation

Not every sleep complaint needs a specialist referral. But certain patterns should prompt a conversation with your GP and potentially a referral to a paediatric sleep physician.

Loud, habitual snoring is the most common red flag for obstructive sleep apnoea in children. About 10% of children snore regularly, but only 1-3% have clinically significant OSA. If your child snores most nights, pauses breathing during sleep, or sleeps in unusual positions (like with their neck extended or sitting up), that warrants investigation. The Sleep Health Foundation provides useful screening resources for parents.

Excessive daytime sleepiness in school-age children is always worth investigating. Unlike adults, who tend to get overtly sleepy when sleep-deprived, children often manifest insufficient sleep as hyperactivity, irritability, poor concentration, and behavioural problems. A child who’s been labelled “difficult” or “hyperactive” may actually be chronically sleep-deprived.

Persistent difficulty falling asleep beyond what’s expected for the child’s age. A 3-year-old taking 20 minutes to settle is normal. A 10-year-old lying awake for over an hour every night despite reasonable sleep habits may have a circadian rhythm issue or anxiety-related insomnia.

Night terrors and sleepwalking that are frequent, intense, or continuing beyond typical age ranges. Most parasomnias in children are benign and self-limiting, but episodes that are unusually violent, cause injury, or persist into adolescence deserve specialist evaluation.

Leg discomfort at bedtime that disrupts sleep onset. Restless legs syndrome occurs in children, though it’s often misdiagnosed as “growing pains.” The key distinction is that RLS symptoms are specifically worse at rest and in the evening, and they improve with movement.

Paediatric Sleep Apnoea

Childhood OSA deserves special attention because it’s common, underdiagnosed, and has significant consequences if left untreated.

The most common cause in children is adenotonsillar hypertrophy — enlarged tonsils and adenoids that obstruct the airway during sleep. Unlike adult OSA, which is typically managed with CPAP, the first-line treatment for most paediatric OSA is adenotonsillectomy. It’s highly effective, with resolution rates of 70-80% in straightforward cases.

But paediatric OSA isn’t always straightforward. Children with obesity, craniofacial abnormalities, neuromuscular conditions, or Down syndrome may have persistent OSA after surgery or may not be surgical candidates.

Assessment involves an overnight polysomnography study — the gold standard diagnostic test. Paediatric sleep studies differ from adult studies in their scoring criteria and interpretation, so they should be conducted and interpreted by services with specific paediatric experience.

The consequences of untreated paediatric OSA include impaired cognitive development, behavioural problems that can mimic ADHD, cardiovascular strain, poor growth, and bedwetting. Research published in Pediatrics has shown that children with untreated moderate-to-severe OSA score significantly lower on neurocognitive testing than their peers, and many of these deficits improve after treatment.

Behavioural Insomnia of Childhood

This is probably the most common paediatric sleep problem that parents bring to medical attention, and it’s one where specialist input can make a big difference.

Behavioural insomnia has two main subtypes. Sleep-onset association type involves children who’ve learned to fall asleep only under specific conditions — being rocked, nursed, having a parent lie with them. When they wake normally during the night (as all humans do), they can’t resettle without those conditions being recreated.

Limit-setting type involves children who resist or refuse to go to bed or return to bed, usually in the context of insufficient or inconsistent boundaries around bedtime. It’s exhausting for parents and genuinely disruptive for the child’s sleep quality.

Both subtypes respond well to behavioural interventions. A paediatric sleep psychologist can work with families to develop structured plans that are appropriate for the child’s age and temperament. The evidence base for these interventions is strong — systematic reviews consistently show significant improvements in sleep onset latency, night waking frequency, and total sleep time.

When to Talk to Your GP

A good starting point is keeping a sleep diary for two weeks before your appointment. Record bedtimes, wake times, any night waking, snoring observations, and daytime behaviour. That gives your GP concrete information rather than general impressions.

Your GP can assess whether a referral to a paediatric sleep specialist is warranted, or whether the issue is likely to resolve with simple sleep hygiene adjustments. Many children’s sleep problems respond to straightforward modifications — consistent bedtime routines, appropriate sleep schedules, removal of screens before bed, and optimal sleep environments.

But if simple interventions haven’t worked after four to six weeks of consistent implementation, or if the red flags listed above are present, don’t wait. Sleep disorders in children don’t resolve themselves, and the developmental window during which treatment has the greatest impact isn’t unlimited.

What Specialist Assessment Involves

A paediatric sleep consultation typically includes a detailed sleep and medical history, physical examination (with attention to tonsil size, nasal patency, and craniofacial structure), and often a sleep study. Some services use questionnaires like the Paediatric Sleep Questionnaire or the Children’s Sleep Habits Questionnaire to standardise assessment.

The specialist will also screen for conditions that commonly coexist with sleep disorders — asthma, allergies, anxiety, ADHD, and neurodevelopmental differences.

Treatment depends on diagnosis, but the important thing is that effective treatments exist for virtually every paediatric sleep disorder. The challenge is getting children to the right clinician in a timely way. Many Australian families wait months for paediatric sleep consultations, which underscores the importance of early referral when warning signs are present.

Your child’s sleep is foundational to their development. If something doesn’t look right, it’s always worth investigating.
