Sleep duration and sleep-wake patterns are closely linked as core components of sleep regulation and development, as evidenced by their joint analysis in clinical reviews [1] and research studies [2]. Furthermore, both metrics are frequently evaluated together when establishing health recommendations for children [3] or tracking developmental changes over time [4].

referenceBathory and Tomopoulos (2017) reviewed sleep regulation, physiology, development, duration, patterns, and sleep hygiene specifically for infants, toddlers, and preschool-age children.
measurementIn the study by Tham et al., the short-variable group began with the lowest sleep duration in infancy and increased as toddlers, but remained significantly lower in total duration than the long-sleep groups at 18 and 24 months; by age 4, total overnight sleep duration converged across all groups, though the short-variable group continued to exhibit the highest variability in sleep patterns.
