Sleep problems in children are extremely common — affecting an estimated 20–30% of children at some point — and have knock-on effects on mood, learning, behaviour, physical health, and the wellbeing of the whole family. Importantly, the right approach varies significantly by age, developmental stage, and the specific nature of the problem.

Newborns (0–3 months)

Newborns have no established circadian rhythm (which develops from approximately 6–12 weeks as melatonin production begins). Normal sleep is fragmented into 2–4 hour cycles, with nighttime waking for feeding being biologically appropriate rather than a “problem.” Survival mode is the realistic expectation. Sleep safety (back to sleep, firm flat surface, no loose bedding, room-sharing but not bed-sharing) is the priority at this stage. Starting gentle day-night differentiation from 6 weeks (bright light and activity during the day; dim light and quiet at night) begins establishing circadian entrainment.

Infants and Toddlers (4 months–3 years)

The 4-month “sleep regression” reflects a developmental shift toward more adult-like sleep architecture — lighter sleep stages increase, making partial arousals more common. Sleep associations developed at this stage are particularly important: a baby who falls asleep feeding or rocking will expect that same condition when they surface briefly between sleep cycles. Evidence-based sleep training approaches for persistent infant and toddler sleep problems: Graduated extinction (“Ferber” method — check-ins at increasing intervals) and extinction (“cry it out”) — both have robust evidence for effectiveness and, crucially, for long-term wellbeing (multiple studies show no adverse psychological outcomes for the child). Fading approaches — gradually reducing parental presence — are slower but accepted by more parents. The approach that parents can implement consistently matters more than which specific method is chosen.

School-Age Children (5–12 years)

Common issues: bedtime resistance, delayed sleep onset, nighttime fears, parasomnias (sleepwalking, night terrors — common in 4–12 year olds due to frequent partial arousals from deep sleep; management is primarily safety). Screen use in the bedroom is the most prevalent modifiable contributor to sleep problems in this age group — blue light exposure and content stimulation both delay sleep onset. Sleep hygiene principles: consistent bedtime and wake time, screens out of the bedroom from at least an hour before bed, cool dark room, wind-down routine.

Adolescents

Puberty produces a genuine biological circadian phase delay — adolescents naturally want to sleep and wake later. School start times (typically requiring waking at 6:30–7am) are chronobiologically misaligned with the adolescent circadian system, producing chronic sleep deprivation. Evidence-based interventions: bright light exposure in the morning (advancing the circadian phase), strictly limiting screens at night, consistent weekend sleep times (social jetlag from very late weekends significantly worsens weekday function). ADHD, depression, and anxiety are highly prevalent in adolescents with sleep difficulties — these should be considered if behavioural approaches don’t improve sleep.
