How Much Sleep Does a Child Need?

Sleep is one of the fundamental pillars for a child's growth and development. During sleep, the brain consolidates learning, the body produces growth hormone (GH), and the immune system strengthens.

AAP and NSF Guidelines

In 2016, the American Academy of Pediatrics (AAP) published official recommendations for pediatric sleep hours, consistent with the National Sleep Foundation (NSF):

  • Newborns (0-3 months): 14-17 hours (acceptable: 11-19)
  • Infants (4-11 months): 12-15 hours (acceptable: 10-18)
  • Toddlers (1-2 years): 11-14 hours (acceptable: 9-16)
  • Preschool (3-5 years): 10-13 hours (acceptable: 8-14)
  • School-age (6-13 years): 9-11 hours (acceptable: 7-12)
  • Teens (14-17 years): 8-10 hours (acceptable: 7-11)

How This Calculator Works

Enter the child's age, total sleep hours in 24 hours (including naps), wake-up time, and number of naps. The calculator compares data with AAP/NSF recommendations and provides an assessment, suggested bedtime, and nap guidance.

Sleep Hygiene for Children

Good practices to promote adequate sleep:

  • Consistent routine: same actions every evening at the same time
  • Proper environment: dark room, quiet, temperature 65-68 degrees F (18-20 degrees C)
  • No screens: turn off devices at least 30-60 minutes before bed
  • Physical activity: during the day, never within 2 hours of bedtime
  • Light dinner: not too close to bedtime
