My ds, who is a normally cheerful, easy-going little boy has started to be rude to me. If I pull him up something, say teasing his sister, and he won't stop, so I ask him to go to his room. He says ' I wont' and runs off sticking his tongue out. He does go in the end but not after shouting no at me. Just now he had his fingers up his nose and I said ' get your fingers out of your nose' and he glarede at me and stuck them further. I collect him from school and the rest of our day is ruined with it. He does it all weekend too.
It's worse when he is tired, but he is not tired all the time!
An advice, is it a stage, and what am i doing wrong? Dh overreacts a bit which doesn't help, or ignores it til I ask for help in dealing with ds( dh is not around much, travelling and working)
