At least 8 hours of sleep.
At least 8 hours of sleep.
A nine year should be getting 9-12 hours of sleep.
Approximately 3,600 hours per year.
10-11 hours every night are the optimum hours of sleep an eight-year-old should get.

They should have 8 or more hours of sleep in a day.
A 14 year old girl should get ad least an 8 hour sleep. If you sleep to little you can get very unhealthy and be kinda grouchy. If you get to much sleep then theres a possibility you can dose off and go into a coma. Keep that 8 hours. Or you can go for 8 hours and 30 minutes. :)
Depends on the length of your "sleep cycles", but generally 7-9 hours.
