According to Dr. Richard Ferber in his book "Solve Your Child's Sleep Problems," an 11-year-old requires approximately 9.5-10.5 hours of nighttime sleep.
I have read many times in book and in people's opinions and all have come up to 10 to 10 1/2 hours of sleep each night . Try not to get too much sleep , you might have a great morning but you will be tired by 4 , 5 at the most .

The most useful time range for teenage sleep is from around 11:00pm to midnight to 10:00 am the next day. So naturally, in their brilliance, the school systems start classes at 7am to 8am, the time of day when teens can be the least alert.
