My 8 year old DD has become very prone to mood swings and is regularly defiant - doing things that she has been expressly told not to. Examples - cycling along side the road (when told to keep in the garden); taking my phone at night to play with under the bed covers. She's also started arguing back in a much more challenging way - lots of 'you can't make me', 'shan't'. Am now often told am a horrible mother, notices are put on her door telling me to keep out etc, etc! In between - of course - she is very loving, full of energy and zing, constantly on the go and buzzing with chat and ideas. Why is she now so difficult to deal with? We take away 'privileges' such as TV/computer and make lots of threats. I feel my parenting skills are all based on negativity at the moment and feel very jaded. It also causes conflict between DH and me. He's tougher on her and gets very angry when she defies him (or blatantly ignores him when she sees him in the morning/evening). I'm probably less harsh with her, but no pushover! Any thoughts on where to go with this? Any one else dealt with a very challenging 8 year old? Help!
