A little background first...My fiance and I have been living together for one year. We are getting married in the summer of 2007. I have two grown sons (24 and 20) from a previous relationship. My fiance has two children; a 14 year old daughter who lives with her mother (he has a good relationship with his daughters mother) and a 6 year old son, "D", who lives with his father and I. The mother of the 6 year old has no contact with her son, other than letter writing which is sporadic at best, as she's incarcerated. She'll be there for another 4 years. Here is my problem. "D" is so defiant that I don't know what to do. He believes he is ALWAYS right, that he is the boss, that he should have what he wants when he wants it, always has to have to last word or grunt or sigh or noise, etc. He will go out of his way to do the exact opposite of what he's been told. I have tried everything. I have tried being sweet and kind, selectively ignoring him, being stern, nothing has worked. My fiance and I have talked about rules and discipline. We are in agreement on this subject and are, for the most part, consistent. "D" still refuses to budge. If anyone out there has had this problem, please help me out. I'm at my wits end.
