It depends on what time you have to get up in the morning; but you should try for 8 hours of sleep at night. b4 theyre kids LOL
Depends on the age of the child. New Born to 3 years old should get 12-18 hours of sleep 3 Year to 5 year olds should get 11-13 hours of sleep 5 year to 12 year old should get 10 -12 hours of sleep 12- 18 year olds should get 8.5 -10 hours of sleep 18 and up should get 7.5 - 9 hours of sleep
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
9:00 becauce 82 year olds need there sleep
A nine-year-old should have about 9-11 hours sleep each night.
A nine year should be getting 9-12 hours of sleep.
