  • Aim to identify the sleep disorder rather than just treating the symptoms

Numerous meta-analyses confirm the link between short sleep and childhood obesity,131415 behavioural problems,7 and poor school performance.11 A population based prospective cohort study has also associated sleep disturbance after 2 years of age with reduced grey matter volume at 7 years old.19

Parents are generally understanding when a child has short-lived or acute insomnia, such as after a period of illness or the birth of a sibling. However, when insomnia is chronic (defined as occurring for ≥3 nights a week for ≥3 …
