Hi All, I am new here and desperate. Our 11 y/o grandson moved to our home a year ago when he played out sexually with his step brother who was 5 years younger. Our grandson was 10 at the time. It would take WAY too much time to explain everything so the short of it is that this child was abused (physically and mentally) by both step-parents and our home is the first SECURE home he has known. His Dad now lives here too since he is divorcing the abusive step-mom. Problem: Grandson's mother has be diagnosed with PTSD and is capable to convince anyone that black is red. She is a master manipulator. We now see this in our grandson who has been in counseling for years. We are all worn out with his constant arguing and twisting conversations so that they work in his favor. We have read the Love and Logic book but the arguing and twisting the truth does not seem to be addressed much in the book. Anyone have a clue on how to handle this child? He is an A student but talks non-stop at school and at home. He wants to stand while eating, interrupts conversations and just pushes us to the limit. He is on medications which have recently been increased because he is growing. Most of the time he is a very good kid but once this behavior begins, it goes on for hours at a time and he WILL NOT lose the argument.
