Hi, I have a tough question, my eldest daughter will be 13 this year and the issue of mixed gender parties is starting to come up. I have no problems with mixed gender parties but am worried about sleep overs. Growing up I had mixed gender sleep overs and my parents had the rule that boys slept in the lounge and girls in the bedrooms. It worked well for us but my daughter thinks I am being old fashioned and that I don't trust her. I am wondering how other parents have handled this one. I don't want to lay down the " It's my house and you'll do as I say" line as this hasn't worked for me in the past. I get the best results when I sit down and talk things through with my daughter but this one has me stumped on how best to approach the situation.
