I have had experience living in communities where ''swarms of all ages'' play together so this community seems ok to me KWIM. We were blessed to always have enough players for baseball, softball, soccer and or hockey. There was seldom a shortage of kids to have some good clean fun. There was "never" ((I want to emphasize that intensely)) any hanky panky. I have sat on my hands while people questioned why teens might be playing with little kids. Well IME it was how the little kids learned how to swing a bat, steal a base, ride a bike KWIM?
But there were reports in MSM about her wandering alone, not with a pack of kids, from the time she was three. As I said last night, it was really helpful to go back and reread some of the earlier articles, and some of the Websleuths posts from the beginning.
