Hi I have never posted here before but am desperately in need of advice from some others who have been through this. My almost 5YO DS has always been one for testing boundaries, but now he has become impossible. Though he is sometimes the boy he used to be, and fun to be with, there are other times when he seems to have deliberately 'forgotten' all manners and rules, ignores us, shouts, hits, and of course is totally obsessed with all that comes out of his bottom to the point it has stopped being in the slightest bit funny...I just don't know what to do. What's going on? Is it testosterone? 'Thinking Time' doesn't seem to cut the chase any more, nor does confiscating fave toys ('I don't care'). He is starting school tomorrow which I suspect will have something to do with it, but I am so worried about him. Any advice?
