Sleep is a fundamental aspect of health and development in children, particularly during the school-aged years ranging from 6 to 13 years of age. Adequate sleep is crucial for cognitive functioning, emotional regulation, and overall well-being. Approximately 25 percent of all children are reported to have a sleep problem during childhood (Owens, J Clin Sleep Med 1:454–458, 2005). This chapter aims to provide an overview of sleep requirements for school-aged children, common barriers to sleep, appropriate screening tools, and prevalent sleep disorders in this demographic. Insomnia is considered when patients have difficulty falling or staying asleep. Obstructive sleep apnea (OSA) is characterized by repeated interruptions in breathing during sleep due to a collapse of the upper airway. Parasomnias include abnormal behaviors and perceptions during sleep. Circadian rhythm sleep-wake disorder in children occurs when there is a misalignment between the child’s sleep-wake cycle and the standard time. Additionally, a clinical case is included to illustrate a common clinical scenario in the pediatric sleep clinic.
