I'm worried about my DS's capacity for violence towards his little sister.
One example: playing happily together. She says something he doesn't like. He contradicts. They bicker with increasing heat. I move over to them, but by the time I get there it is too late: he is trying to hit her and as I physically remove him to take him to time out, he manages a kick to her head. :(
Time out didn't do much. He genuinely seemed to believe that it was her fault he kicked her, because of what she said.
Another example: she was playing with a stick. He thought it was his stick because he'd played with it the day before and tied a bit of string round it. I didn't realise this. He said to her, "Give that back; it's mine!" I said, "She's playing with it at the moment," and he launched himself at the stick and broke it into three pieces. DD burst into tears and DS said, "There. Now you can't have it." We were out; the only thing I could think to do was put him in the car for 5 minutes (we were within sight of the car during that time), which was totally pathetic as a consequence.
I know I'm coming across as feeble and weak, but I really struggle with thinking on the spot and coming up with an effective consequence. I have done time out fairly consistently since he was small; it's worked well with his "selective deafness" but I can't kid myself any longer that it's working for this.
Often by the time I see the danger coming it's too late. And as soon as he's done what he wants to do, it's over and he often says sorry sweetly, does his 5 minutes in time out, or clears up the mess he's made, with a smug air of having got away with it.
I suppose I have two question: Is this behaviour normal? And does anyone have any advice how I can deal with it effectively?
