I don't mean disciplining as such because that sounds abit extreme, but just things like what do you do when he does something bad - eg. sometimes he loves to just scream, I say "No" which he sort of understands but he laughs and screams louder and louder, runs round the house screaming etc. and then I don't know what to do. Sometimes just holding him still, making eye contact and saying no works, but sometimes he just carries on more and more. It's mainly that sort of thing I am having problems with, but in different ways - like today he sat on the book I had on my lap, so I moved it to my side, and he rolled on it - basically kept getting on top of it whereever I put it (thinking it was a game) and I didn't know what to do to tell him he shouldn't do things like that. In the end (after many nos and it getting very out of control) I put him on the floor and he looked sad and toddled off. Do you even bother with No at this stage, or is it all about distraction etc? I hope that all makes sense Thanks
