Hi I understand exactly. My son is 3 1/2 and the debates finally ended. The only thing that worked was to tell him that no matter what he calls it, it is still ___ Then walk away :)
We have 2 other children and we did notice an increase in this when the latest was born, it was his way of getting more attention. We started more one on one and it gradually faded away.
I think the need to be immediately obeyed is just a man thing. My husband, after a lot of nagging to try it my way, finally did and it worked, imagine that! ;P I always remind myself that I have 4 children, 3 little, 1 big and try to be patient. Anyway, my husband does bedtime and he found that it worked really well if he gave my son choices on the important things. Like you can either do as I say or lose a story or maybe a toy he likes to have in bed with him and then if he still didn't listen follow through. It didn't take long for my son to understand that what Dad says goes. Bedtime goes a lot smoother now.
Good luck! and keep repeating "this too shall pass"
