S.A.
My son is 11 and a few weeks ago he really started giving me attitude and being mouthy also. I was over reacting to everything. It's hard to have your child act this way I know, but try not to react to everything. Try to just praise on the positive things she does. I know a lot has to do with the age and all the changes they are going through. My son is back to normal (Thank God!). It hurts, I know I was very upset. Things will change and if she gets out of hand you have to use tough love. Take what's important to her away so she knows you are not playing around. She will come around. Good Luck.
