At what age can a child babysit in illinois?:
Contrary to what most people think, most states do not have laws addressing minimum ages to babysit or minimum ages that children can be left alone.  Unless someone can cite a specific Illinois law, chances are the answers you get here are of little value.  While 15 or 16 might sound like logical numbers, that doesn't mean the answers are correct on the law.

I don't know Illinois law nor am I going to make up some number for you.
