What time should children go to bed? There is no single perfect bedtime because age, wake-up time, naps, school schedules, and individual sleep needs all matter. This guide explains recommended sleep ranges from infancy through the teenage years and offers practical bedtime examples for toddlers, preschoolers, five-year-olds, seven-year-olds, ten-year-olds, and older children. Parents will learn how to calculate bedtime by working backward from the morning wake-up time, recognize signs of insufficient sleep, build a calm routine, manage screens, and adjust weekend schedules. It also covers persistent sleep problems and breathing symptoms that require medical advice.
