My oldest child Evan is soon to be 6 (Nov. 21). Sometime I think of him as the parental test child since he is our first and everything is new.
We have ventured into the Why do I have to do what you say? and I don't want to! territory. He doesn't understand why he has to do what we say if he doesn't want to. Poor kid, such a hard but very important lesson to learn in life.
