Look and see what this article (excerpt below) has to say about sleep and kids:
School-Age Children and Preteens
School-age kids need 10 to 12 hours of sleep a night. Bedtime difficulties can arise at this age for a variety of reasons. Homework, sports and after-school activities, TVs, computers, and video games, as well as hectic family schedules might contribute to kids not getting enough sleep.Lack of sleep can cause irritable or hyper types of behavior and may make it difficult for kids to pay attention in school. It is important to have a consistent bedtime, especially on school nights. Be sure to leave enough time before bed to allow your child to unwind before lights out.
Teens
Adolescents need about 8½ to 9½ hours of sleep per night, but many don't get it. Because of early school start times on top of schedules packed with school, homework, friends, and activities, they're typically chronically sleep deprived.And sleep deprivation adds up over time, so an hour less per night is like a full night without sleep by the end of the week. Among other things, an insufficient amount of sleep can lead to:
- decreased attentiveness
- decreased short-term memory
- inconsistent performance
- delayed response time
Teens also experience a change in their sleep patterns — their bodies want to stay up late and wake up later, which often leads to them trying to catch up on sleep during the weekend. This sleep schedule irregularity can actually aggravate the problems and make getting to sleep at a reasonable hour during the week even harder.
Ideally, a teen should try to go to bed at the same time every night and wake up at the same time every morning, allowing for at least 8 to 9 hours of sleep.
