Everything you need to know about this topic.
The amount of sleep your child needs depends mainly on age. Children ages 1 to 2 generally need 11 to 14 hours in a 24-hour period, including naps. Children ages 3 to 5 usually need 10 to 13 hours, including naps. School-age children from 6 to 12 generally need 9 to 12 hours, while teenagers need around 8 to 10 hours. These are ranges rather than exact targets. Some children function well near the lower end, while others need more. Pay attention to whether your child wakes naturally, remains alert during the day and manages emotions well. Regular difficulty waking, irritability or daytime sleepiness may suggest that bedtime needs to be earlier.
