Ds1 (4 next month) has always been a bit of a handful. He has bags of energy and needs lots of stimulation (although he can play quietly by himself when he wants to). He's currently at the 'Why?" stage ie he never shuts up! He is also really badly behaved a lot of the time. Apart from being mean to his younger brother (15mo) it's mainly low grade stuff (kicking & punching me, making a fuss about his food, being cheeky, not doing as he's told, shouting, spitting etc) but constant. I'm pretty exhausted most of the time so I usually end up exploding. I do the usual sit on the stairs routine, or take away favourite toys but often he just seems to misbehave despite himself. When I challenge him he either laughs or says he can't help it. A typical exchange, say after he's been mean to ds2 might be:
Me: Do you think it's right to hit your little brother?
Ds1: No
Me: So why do you do it?
Ds1 [obviously upset & frustrated] : I don't knoooooow! I can't help it!
What I want to know is, is there a developmental stage they go through at this age which makes them unable to control their actions? Or is there something wrong with him????
