'I would be inclined to let her go, with a phone, and when you call, ask her questions where she will be able to give Yes or No answers. Do not expect an 11 year old (or older teen either) to be able to say 'Take me home, I hate it here and I am out of my depth' straight out over the phone to you. They are far more likely to gut it out than ask for rescue. Tell her in advance that if she decides to come home you are not going to interrogate her, that you will trust her judgement.'
'I agree it is important to allow girls the opportunity to socialise for the reasons Lesley mentions. Boys' friendships have a different dynamic. With girls, the 'who's in' and 'who's out' aspect of life can't be dismissed and expected to disappear as mothers tend to want to see happen. It doesn't go away just because you wish it wasn't so.'
Oh yes, ExoticFruits, I actually do trust the judgement of all four of my DDs, and my DS too, and I have encouraged them to use their judgement in carving out their social lives. I have a don't ask don't tell policy when it comes to leaving parties and have picked them up at all sorts of odd hours. They have turned out just fine. My oldest DD will graduate from a US university next summer, having navigated her way through high school and four years of college without incident as far as I am aware. DS has just set off on his own university adventure. The rest I see every so often
between their many social engagements/sports/drama clubbing and their visitation with their father every second weekend.
What is wrong with assessing people? If I went to a house and smelled pot or caught sight of something x-rated on the TV or realised there that there was actually no adult present but instead older teens at a sleepover for 11 year olds, then I would tell my DC the party was off as far as they were concerned. I agree with you that parenting is a long process involving letting go of your children and trusting them to sort out their own lives for themselves. However, this is done in the case of my DCs with input from me as to how to go about making their decisions.
You seem to be pretty hot around the collar about the other parents' motives for having a sleepover. I don't get why you are so invested in beating me about the head with your scorn of the idea that parents can use parties to curry favour/ help their child's social life along/ maintain their child's popularity/ get to know people at the start of a new school year. I have seen just about everything in my many years of observation of the social lives of girls. It has been almost 11 years since DD1 turned 11; that translates to a lot of different schools, friends and friendships and a lot of parties over the years.
