My thirteen year old is asking to not be left with a babysitter in the evenings any more and to be allowed to be home alone. I am a lone parent and my child is an only child. I rarely go out because I don't want to call in favours from family too often (we don't have much family around) so if I were to leave her home alone, it would allow me to have more of a social life. She is sensible (bar enjoying the opportunity to eat snacks and stay up later) and is used to being home alone for a few hours in the daytime no problem.
At what age is it reasonable to stop using a babysitter and how late would you feel comfortable staying out if your teen was home alone?
