While there is no law to say yes or no, the authorities are not going to look at this favorably. There are several reasons:
Most people believe a 12 or 13 year old can be left alone for a few hours in the day.
The 9 year old is going to disobey the ten year old.
The 10 year old is not old enough to know what to do in an emergency.
It depends on how Mauture your 12 year old is.
no of corse not
Depends how responsible the 15 year old is in your point of view, and if you think they'd be responsible enough to have your childrens' lives in their hands.
2 or 3 children an hour
10or older
As long as you can trust them. I am 13 I have been babysitting since I was about 11. You should have a way to contact the kid and have established and emergency exit plan.
Depends on the laws of the country you're in. Often there is no legal limit on siblings looking after each other. But if things go wrong, the parents can be charged with negligence.
If you have siblings then play with them if not play with some toys or watch TV that's what my 8 year old brother would do
You have to be 18 in Ohio, the good news is the 17 year old can be married with parental consent:)
yes
No. Age of consent in Ohio is 16.
Depends what year...
