Legal age for child to be left alone w sibling nc?

There is no legal age for babysitting, however as I have found from searching it seems that most people have not found kids to be mature enough until they are at least over twelve. This would probably be wise, considering that you will want the people you are babysitting for to know that you are old enough in their minds. Also, if something bad happens when you are left alone under the age of 12, it could be considered your parents fault, so I would wait until you are over 12 to babysit.
