Q: Our 15-year-old daughter is very demanding and, to be honest, self-centered. One of the things she does is ask one of us for something and demand an instant decision, as in, "Can I go to the mall with my friends?" If she doesn't get the right answer, she begins to yell and become disrespectful and/or she goes to the other parent (in person, phone, text), but cleverly fails to tell him/her of the first parent's decision. That, of course, causes tension and sometimes conflict between the two of us. We feel caught between a rock and a hard place. If we tell her that she must wait on a decision until the two of us can collaborate, she begins to throw a temper tantrum. On the other hand, if one of us makes a unilateral decision, we often regret it. Any suggestions to help us resolve this?
