I don't know exactly how common this behaviour is in young children (I suspect it's mainly boys), but ds, who is nearly 3, seems to be totally unable to stand/sit still most of the time. He's ok at home, as he will sit for quite a long time to watch a video and plays quite well on his own, but yesterday afternoon I had to pop out to the shops and he was a nightmare - all in the space of about 15 minutes. If I'm standing at a counter waiting to be served, ds will be jumping around/touching things/opening and closing the shop door, you name it he'll be doing it. In one shop he was holding a small toy in his hand and proceeded to bang it loudly against the counter while I was trying to speak to the shop assistant, and telling him to stop it/come here/don't touch/keep still, is just to no avail at all. He can't just stand there - he has to be jumping up and down or running around the shop inspecting everything. It gets me down because I can feel myself getting tense, I worry that he might break something and I hate the 'disapproving looks' that he occasionally gets. Amazingly enough he actually sleeps very well, but seems to have ants in his pants the rest of the time. Does this kind of behaviour sound familiar to anyone? Thanks for your help....
