That doesn’t quite match-up to when I was 15. :-|
If your child is unable to handle:
a blown fuse or any other power outage
a backed up toilet
a small kitchen fire
a stranger at the door
a minor injury
a minor illness
or any phone call, email or facebook contact from people you dont know.
They should not be left alone over night.
I babysat a lot at 14 but the parents gave me cell phone numbers and were never more than 20-30 minutes away.
I was 16 and had a driver’s permit before my parents left me to care for my baby sister alone for the entire weekend!
