The yelling and aggression sounds like my sons’s behavior when something is causing him anxiety. In my experience it’s not what I’m asking him to do that is the source of the lashing out, but it’s his anxiety about something, often unrelated, that’s causing the outbursts and defiance. When I can get to the root of the problem and address that, the behavior problems usually handle themselves. The other behaviors sound like impulsivity taking over. My son is highly impulsive. We manage with medication and often a ramp up in impulsive behaviors means it’s time to revisit the meds. Hang in there!
