I too am a step mum of an 11 year old. He has come to live with us because of his behavior at home. Now, my husband and I have seven children together. My children are no angels but they have respect and I can say they are pretty good. My stepson is having a hard time adjusting to the rules of our household and does not like to listen to me and gets into fights with the other children so I can understand you when you say you are frustrated because I too am. I am being very patient with this situationbut it is hard when my husband gets very sensitive when it comes to him.
