When my child and her friend rode the school bus to kindergarten, a 6 yr boy on the bus (from a very unstable home of course) started saying very sexual things to them - he obviously had seen nude pictures and maybe even porno...he said things no child should ever say, or know about.
The little girls didn't have any idea what he was talking about, but they knew enough that he was scaring them, and saying bad things.
I called the school, spoke to the principal and told the teacher....they were all "working" on "the problem"...this family was a mess - I insisted my child NEVER sit by him on the bus etc.....
I'll never forget the sick feeling I had talking to her about why he said those things....and I taught her some important survival skills to get him to leave them alone.
She always had my complete permission to tell him to Shutup, & kick, hit & scream @ him if he ever touched or threatened her... (thankfully they moved away).
I know what you mean about the sick feeling. I probably didn't handle it like the modern moms would.. I remember telling him to never do that or his teeth would fall out and if anyone ever did it to him his pee pee would fall off. I probably scared him for life but that's what moms did then. Scare the hell out of them. He is a grown man now with teen agers so I guess I didn't do such a bad job raising him. Three it too young to be having to talk to a kid about this kind of stuff. I just wanted to let people know, this is nothing new. It's been going on a very long time but we hear more about it because it ends up in the courts and the media.
#1 - Kick or punch them between the legs
#2 - If you can't kick or punch them grab, squeeze and twist very hard what they had between their legs
#3 - If they attempt to stick something in your mouth bite really hard while grabbing and twisting other parts.
#4 - No matter what happens, tell mom and grandma, let them tell dad and grandpa.
I'll let the reason for #4 to your imagination.
