How much sleep does a 9 year old boy need a night?
A nine year old child needs about 9 to 11 hours. Every child is different as some would require more sleep than others. You should however note that most children require a lot of sleep ? mostly more than a parent would allow.
9 to 11 hours of sleep would be fine.
Around 10 hours more or less. My brother is that age and he goes to bed at 9:00pm and he wakes up at 7:00am.
