I think 13 is a mature age for some children (especially girls - but I'm sure I'll come under some criticism for saying that). When my youngest (who's birthday is in October and is one of the eldest in her year) moved to a primary school, which was on our doorstep, I allowed her to walk home to an empty house and remain alone for an hour - until I got home from work. I made the neighbours aware and she really enjoyed the responsibility. I didn't allow her to stay on her own, during the evening, until she turned 14 and that was only on the very rare occasion that hubby and I both went out. Having said that, I was raised by my father only and I was cooking meals, washing, cleaning and looking after myself at 12. I grew up feeling much more mature than most of my friends and I really think it has made me a better parent to my own children. My Dad was a star but he worked all hours to raise my me and my sister .........love him! If you live in a safe enough area, see it as allowing her to mature. Good luck
