I have a 9 yr old girl who's extremely bright. By all reports, her behavior at school is great - she's respectful and considerate of others. She takes responsibility for her own schoolwork and receives great grades.
As soon as she comes home, she becomes an angry, rebellious child who "wants to live somewhere else" and "hates everyone". Her attitude towards her parents and siblings is horrible. She frequently refuses attempts to discipline her and ends up being punished even more. We have tried removing privileges, taking away toys, time-outs and even spanking. Her response is always "I don't care - do it." This morning she told me to "kick her out of the house".
She's behaved this way since the "terrible 2s". She usually apologizes for her behaviors at the end of the day (at bedtime). We're at our wits end!
