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 .
You should sleep six hours in the morning.
A preteen should get around 9 hours of sleep.
They need at least 4 hours sleep plus. If they are still growing then it is advised to get 8 hours, but because of girls hormones when growing up this may agrivate there sleeping patterns. It is best to see when they are tired and need sleep.
They should have 8 or more hours of sleep in a day.
if you mean how many hours you should sleep in a year it would be 3,650 hours of sleep for a regular year not a leap year
