It teaches you how to enjoy being a parent. That will really work for me. But reading about a new technique is not the same as practicing a new technique. Practicing a new idea means changing your behavior. Any change in behavior means changing habits, and habits are not easy to change.
Old habits are more comfortable than new ones.
As you continue with this book, you will be learning about successful parent behaviors, reading about strategies and techniques that you need to use more, and behaviors that are counterproductive. You will need to cut down on these behaviors. You will also find that many of your present ideas are appropriate and need no change. As you read, make a list of behaviors that you need to practice more, behaviors you need to practice less, and behaviors that are appropriate and should be continued. Since it takes about a month to develop new habits, review your list two or three times a week for the next four weeks.
