No, but eight to ten hours is optimal for a child of that age.

As a person gets older they require less hours of sleep and can actually function better on a lower number of hours. Typically when you get older you have a harder time sleeping and only get about 4-6 hours of sleep a night.
12 year old girl needs only 8 hour uninterupted sleep good luck
A fifth grader should get 9 hours of sleep. Obviously, this is hard to maintain from a night-to-night basis. However, try to make sure a fifth grader gets 9 hours of sleep to be at his/her best.
how many hours of sleep does a elephant sleep
1,260 hours in total.
people need between 8 to 11 hours of sleep depending on their age and health. For example; a teenager needs a minimum of 9 hours of sleep a night while an adult only needs between 7 to 9. The more sleep a person gets, the better it is for their well being.
Not necessarily - the 'eight hour sleep' is a myth. Every person is an individual - while one person might need 8 hours sleep each night, another might only sleep for 7.5 hours. I, myself only need just over 6 hours each night - and have had this sleeping pattern ever since I was a teenager (over 30 years ago !)
Any person needs on average a good 6 to 9 hours of sleep; teenagers often sleep 10 or more hours. Averaging only 2 hours per night means your body does not get restorative sleep. But the cause of insomnia must be determined as there can be many causes. Talk to your parents, ask for a doctor appointment. You might need a Sleep Study.
