I get so annoyed when people label this as Sexual assault! The boy was 6, he can't be 'sexual' he wouldn't have urges. He's simple being silly or perhaps copying behaviours he has seen or been subject too (which of course is very sad).
My Ds is 5 and does silly things like try to touch my boobs and bum, go for grabs on me and even touch his brothers privates when he's naked. He does this as a joke, for a reaction, not as sexual assault. I'm trying to teach him not to touch other's private parts etc, but what if he does at school next year!! I'm freaking out that police would be called and I would be labelled as a perpetrator myself!
