It really depends on the kids. Some kids I can have here for a few days, others wold drive me mad after a couple hours
DD went to a friends house yesterday, not a party, just a little get together. There are 5 of them, and she was there from 2.30 till 8.30. They are such a nice bunch of girls though, that it wasn't a bother. They're gorgeous kids. If it had been the group she used to hang out with, that would be a whole other story. You might remember my birthday party sleepover hell story from earlier in the year, when I sent one of the girls home for being a PITA.
