So, my DS is nearly 9yrs old. Also have a very bright 7yr old DD. They get on quite well (as much as any siblings) and my DS is certainly not stupid but he insists on acting like it!
Lots of very unfunny toilet humour, slightly badly handled attempts at sarcasm towards friends, pretending to our friends that we get drunk "all the time" (I'm virtually teetotal and DH only drinks couple of glasses of wine after kids go to bed at weekends!) and just generally acting in an idiotic manner that makes him a) seem very immature and b) gives the impression that he's a rude moron!
I am certain that some of it is insecurity and him feeling the need to act the fool, possibly in comparison to his very bright and very articulate little sister, but I can't get across to him that actually if he stopped doing that he'd come across as a much nicer kid and that if he doesn't other children / grown ups are going to get a completely wrong impression of him.
I'm worried that his friends, who seem a bit more mature of him, are going to get sick of him soon, and that any adult seeing how he can behave at times (and it's not ALL the time thankfully!) is going to steer well clear of him.
Anyone else dealt with things like this and what do you do about it? Or will he just grow out of it?
