Discipline and The Act of It

I think we need help. Our opinions differ sooo much. We have no idea how to discipline a child *together*. We don't agree one bit. And I am ready to give up. Fine. If you don't like how I do it, then you do it. All by yourself. Don't come in and tell me to apologize. I'm not sorry and I think he deserved it. I am tired of being told not to do something right in front of small child. No wonder he cries, "Daddy, daddy!" all the time. No wonder he doesn't care what I say. I think we need to have a series of "consultations" with older, wiser couples who have had years of experience raising and disciplining children. Maybe I am too strict. But if I am, I would like to know how I should be doing it, and still get my child to listen to me, to sit when he is supposed to sit, to be quiet when it is time to be quiet, and to respect me, and those who need to be respected. And I think we need to be able to agree on how to raise this boy. Right now there is still time to get our act together. But we don't have long until he could morph into a monster who knows exactly how to divide and conquer his parents to his benefit. So, yes. I am asking for help. How do we come together as one parental unit and actually begin acting like it?
