My 4 year olds behaviour is so, so exhausting. He's so difficult about everything, he argues about everything, he freaks out and scratches me all the time,occasionally bites me too. He tells me he doesn't love me. I've just left a doctors appointment about his behaviour and how much I'm struggling and proceeded to stand in the car park for 45 minutes trying to go home with him just undoing his seat belt and climbing out every single time I tried to drive off. I just don't know how to parent him. I don't know what to do and I'm exhausted and so so fed up.
