My DS (3.4) has started refusing to do things he is asked (it starts with getting dressed in the morning and ends with getting his pj's on). He won't do a thing unless he wants to. It's really getting me down. I cry a lot in the other room. I can't get him to come to the table, wash his hands, have a wash when in the bath, have a dirty nappy changed etc etc. The list is endless. I tried stickers but he only wanted one a day ("I already got one mum"). I've tried the praising the good which he accepts like it was no trouble. When we are out and about he is as good as gold. When we are home it's a different story. Any advice?
