Here's the lowdown on how much sleep kids need at different ages, according to a consensus group of 13 sleep medicine experts and researchers who developed the recommendations: Infants 4 to 12 months - 12 to 16 hours of sleep every 24 hours (including naps). Children 1 to 2 years - 11 to 14 hours of sleep every 24 hours (including naps). Children 3 to 5 years - 10 to 13 hours of sleep every 24 hours (including naps). Children 6 to 12 years - 9 to 12 hours of sleep every 24 hours.
Sleep and Toddlers (1-2 years). Toddlers need about 11-14 hours of sleep in a 24-hour period. When they reach about 18 months of age their naptimes will decrease to once a day lasting about one to three hours.Naps should not occur too close to bedtime as they may delay sleep at night.leep and Newborns (0-3 months). For newborns, sleep during the early months occurs around the clock and the sleep-wake cycle interacts with the need to be fed, changed and nurtured. Newborns sleep a total of 10.5 to 18 hours a day on an irregular schedule with periods of one to three hours spent awake.
