My son turns 8 in March. We recognized early on that he is dyslexic and he gets superb support and has come on leaps and bounds. He is a good boy at school- he's interested to learn and has lots of friends. People always comment on how good he is. This behaviour extends to home ONLY when he is doing what he wants. He is a sweetheart until you ask him to do something he doesn't want too. It can be anything from homework to brushing his teeth.He is rude, he talks back- he has even started shoving me. I have to supervise him to do simple things or else he gets distracted. He makes holes in his clothes or the wall whilst he should be doing his homework and then can't answer why he does it. He gets over emotional and cries after doing something naughty. He is angry, short tempered, nasty to his little sister, impatient, unable to concentrate. He gets frustrated very easily. He can't sit still unless it's to watch something on he wants too. It's escalated in the past year. I stay as calm as possible and he gets 7 mins time out when he is naughty but nothing changes in the long run. Is it a phase? Or something else? It's as though he physically can't do as he is told. Like impossible to resist the temptation of doing the opposite. Please help.
