Your child should go to bed at:

Sleep Needs by Age Group

  • Adult: 7 – 9 hours
  • Teenager: 8 – 10 hours
  • Child: 6 – 12 years: 9- 12 hours
  • Child: 3 – 5 years: 10 – 13 hours (including naps)
  • Child: 1 – 2 years: 11 – 14 hours (including naps)
  • Infants: 4 -12 months: 12 – 16 hours (including naps)
  • While all sleep calculations are based on average length of cycles, your child’s body is unique, therefore they might need more of less sleep, or have cycles that are irregular. However, most children require 8-12 or more hours of sleep each night. In some situations, you will find your child is content with much less.
  • The most important component of ensuring your child wakes up happy and restful is using the sleep calculator to make sure their sleeping and waking pattern following the natural sleep cycle. When you wake up your child when they’ve just finished a cycle, they will be more likely to wake up without feeling groggy, grumpy, or disturbed.
  • The Sleep Calculator for Kids works out the best time for your child to wake up by counting sleep cycles. <Each cycle for a X-year-old lasts around X minutes. >
  • When your child wakes up grumpy or disturbed, that means you might have woken them up mid-cycle. The best way to wake your child up with smiles each and every day is to use the Sleep Calculator results to show wake-up times that are timed right between the cycles.
  • Note that most children take some time to actually fall asleep, so their cycle hasn’t started yet. The typical time it takes an average child to fall asleep is around 10-15 minutes. We’ve gone ahead and factored this into your Sleep Calculator answer.
