Like I said, some of you don't have a strong willed child.
My son was similar to Bubba. He listened and was fairly easy to discipline. At the time I thought parents who had difficulty with their kids simply weren't parenting properly. Then DD came along. LOL! Very strong willed. You could give her three choices and she would not like any of them. In that case, we would abruptly leave, but that's not always an option. I remember going back to the van many times for Time Outs with her, loss of privileges, etc. but even then she would carry on. Sometimes you just need to choose your battles. She is still our challenging child, despite the fact that we're not lazy, spineless parents.
I remember reading an article written by Dr. Sears a few years ago. He went on to explain how he and his wife, both pedicatricians, couldn't understand why parents had such problems with their kids. After all, they had 3 children at the time and with proper discipline, they were well behaved. Then he said he and his wife had an eye opening experience when Baby #4 was born. Very high maintenance and strong willed! Then he and his wife "got it" and were more empathetic towards other parents who had strong willed children.
