Wow, you have to be 14 to be home alone for a lengthy period of time in Illinois? That's stupid. Maybe like, overnight, or for any meals that require substantial cooking, but my parent left me home alone with my younger brother way before then.
It's not very hard to make breakfast or lunch, and any issue that would need a parent to solve is probably something they would have to call 911 or bring us to the hospital for anyways.
