Hi, any advice welcome. I have son, turning 11in May. Secondary school looming. He’s fine most of the time, when it’s all going his way. As soon as it isn’t the toddler tantrum comes out. Chucking stuff, shouting and general unpleasantness. He has learnt he can control a situation with volume and aggression. Advice on how to regain control and help him be a person who can control the temper? Thanks In advance 👍
