My 9-year-old girl has developed some very challenging behaviour that I'm at a loss to deal with and I really need some advice. She's currently wailing and screaming - literally just shrieking at the top of her voice - because she hasn't got her own way over something (for valid reasons). She is out of control. I'm trying to get her to go to her room but she won't and I can't physically get her there.
She's good at school, but the mornings are a nightmare - she just won't get out of bed and every morning we're late, no matter what threats/promises we make. She's just so rude and unpleasant to us - particularly me. In the afternoons, she's fine again.
I can't help but think that this must be mine/my husbands fault but I don't know what to do - any advice?
