I'm really curious as to what the other children are doing, and if the teacher's been really watching the whole situaion unfold (as opposed to just seeing the one action, and to the teacher's credit it can be very hard to see the whole situation-I'm not trying to say the teacher is bad or doesn't take care of the students.) then she'll know. Are the other kids getting upset, or is it a joke for all of them? Maybe he's doing this because he gets such a big reaction. I don't know if they're taking that into account. If he's an average student, then he's not getting praise for perfect grades, nor is he getting more time spent on him because he needs help. He sounds to me like he's much more likely to be a class clown in the future, so I wouldn't listen to those who say this is leading to groping women/girls, etc. He's not thinking with THAT "brain" yet! He's a child! And no matter how grown up we want to make our little boys, whether it's trying to teach them to aim into the toilet or quit talking about butts or farting, the truth is that they are still children (and my dad was the first one to talk about farting with my son, and he was in his mid 50s at the time so take what you want from that). The fact that this has only been the past month makes me wonder even more what's really going on? Maybe over Christmas break he really enjoyed being with you and now he's a little sad about leaving you at home? Maybe a student moved (left or joined the class) during break and he's adjusting to that. Maybe they got back from break and another kid did it and everyone laughed so he's picked it up, trying to get the same reaction. Or, like someone else mentioned, maybe it's just something he's doing right now that is funny to him. And the truth is that we can tell a child not to do something and that it's bad, but if they don't understand why, they're very likely to do it again. He's not thinking "someone might interpret this as molestation and I don't want to offend anyone in that manner." Again, he's just a child. Those are concepts he won't understand. And even teaching him about personal space can help (we had to go over this with my son when he started acting up when his sister was born), but if he finds it all funny, he's not likely to never do it again. Just a thought--when did you get engaged? That could have an effect on his behavior if that was a Christmas thing--it could really be that he needs a "mommy and me" date. I did that with my son after Lil was born and explained to him that I still loved him more than anything in the world, but that I also love his sister that way too. I just asked a few questions and he told me, crying, that he missed me. It broke my heart. He wasn't quite 3, but it really affected him, even though he had 8 months to prepare. Maybe there's something like this going on, something that makes him want this attention. Or again, maybe he just wants attention (most people do like attention), or he's just being a little boy. The date could be a sports game, a meal, a miniture golf place, etc...just some time to focus on him. I'd try that before taking him to a counselor. I'd also request a meeting with the teacher and principle to find out how the other kids react to him or any other differences in his school life that may have taken place this month. Good luck!
