My 9 yr old stepson plays his Mother to the nine's. We both have to repeat ourselves several times to get things done. His behavior at school is good, however as soon as he get home he goes crazy, not listening to instructions cutting in on conversations, more or less being overly spoiled. His Mom I and I dont see eye to eye on his punishments when these things get out of control. As the youngest child from her late husband, I feel she is protecting him,sheltering giving in. I'm on the other hand a more strict and direct. She gets very upset when I step in with punishment, thus leading to huge arguments. Our 3 yr old which is ours together in controled by both of us without issue. I just need some advise.
