I am new to this parenting teens thing. My step son has been with us less than a month and the honeymoon is off. I have asked him 4x to get his planner signed off by his teachers, and he says "yeah" but doesn't. He does martial arts, nd I told him he couldn't train because he failed to do as he was told. I feel like that is a fair consequence. There is another issue we are dealing with. We live in alaska and currently it is -30 below. He has been leaving his window open. Last night my husband told him to shut his window and not to open it. He shut it, but today he had it open again. My thought is the next time he leaves the window open we take his door off so we can monitor it better. Is this too harsh? Any suggestions?
