I didn't have these books when my kids were little. Dr. Spock was the thing and some of his ideas didn't fly.
However, consistency and love with a firm hand (not spanking) did keep things normal. If I was too lenient with rules things with my son did not work so if I kept a certain amount of tightness to his discipline it worked. My daughter was the opposite for discipline.
Repetition is how children learn something by doing it over and over again until it sinks in. So you as the parent have to remind them a whole lot in the beginning and but as much as they get older but you still have to be the parent. You can be friends when they are in college and out on their own.
If you do have to discipline, asked the child why it happened so that they know and experience the whole concept of the punishment whether it is a time out, a grounding or a spanking if need be.
My philosophy was that I tell you once, give you a warning and the third time you are mine -- like baseball. They both got to understand when they were being too much. All I would have to say were a few key phrases and they would straighten out and change their attitudes. I always followed through on what I would do and they knew it.
Today my children are adults. They have both thanked me for loving and teaching them and being mom who they could come to with any and all problems and issues. I got a lot smarter for my son when he had a son but prior to that I was on the "mom don't know anything" list. It some times takes years before you see the results of all of the training and guiding you put out but it is so worth it.
Good luck with your books and discipline and loving of your children.

PS Not every style will work with every child. The key is to have mom and dad on the same page backing up each other on what was said to the child because they will try to play ends against the middle to get what they want. The classic "What did your (mom/dad) say?" "Well that's what well will do.
