This book was amazing. I always wondered why I seem to get along better with my son than my daughter. After reading this book, I realized why. My personality is INTJ (Introverted, Intuitive, Thinker, Judger), my son is an ISTJ (Introverted, Sensor, Thinker, Judger), and my daughter is an ENFP (Extroverted, Intuitive, Feeler, Perceiver).
I spoke to my ex who I think is an ISTJ, and he said that he also clashes with her all the time. The book teaches way to get along with your children who have different personalities than you. This morning I tried one of the tips she gives. I was trying to dress my daughter, and I said, "Put your clothes on." My son did it right away, and my daughter started crying. I said, "Let me dress as you as a fairy princess." She stopped crying and put her clothes on with no issues.
Definitely get this book. It will help your parenting style.
