Hello. I am at a loss with my DS. He is the most kind and gentle soul one minute and when things aren't going his way he completely stops listening to what he's being told. I have tried everything....reward charts, thinking chair, removal of favourite toys. Nothing seems to resonate with him. Can anyone offer some advice if they've been in this situation? He's 4 years old and is an angel in school according to the teachers so maybe he saves it for me
