My 7 yr old daughter is difficult, don't know what to do. She is disrespectful to me, fights doing homework, and screams and cries when she doesn't get her way.Also, can act up in stores. My daughter is good at school but when she comes home she is a different person when she gets home. When she home she can be good in ways when they don't have school. I do not know what i do i try to talk to her but she does talk about it. She also get to the point that she throw thing and hit me what to do?
