We have 8 year old DS and are really at the end of our tether. He cannot control his anger. For example, tonight he was playing a game on the phone whilst dinner was getting prepared. We told him in advance that the phone will go off when dinner is ready. Dinner is ready he doesn't stop playing. We explained to him that the phone has to go off, he procrastinates further.
Explained that this it his last chance or phone will go away. He doesn't listen, we take phone away and he completely kicks off. Screaming, shouting, hitting, kicking. He knows any form 8f violence has consequences. No dessert, toys taken away that he throws etc. But it doesn't make a difference. Tantrum tonight lasted for over an hour. He kicks off easily at home. It happens pretty much every day at some point.
We have spoken to school about it, several times, but they don't have that problem with him so don't it really serious. I am so exhausted and absolutely clueless what we are doing wrong?
