This book really made sense to me. It challenged the way that I already think of my two children - even though one is still in utero. I have always thought that siblings are meant to be different but same, meaning one will be organized and one will be chaotic. One good a math, one good at reading. Etc. This book really challenges you NOT to perceive of your children that way and to allow them to grow as separate individuals, in relationship to no one else. It also admonishes that we hear them out when they feel resentment towards one another - which is natural - so that the resentment doesn't fester and grow.

Warning: This book will also dig up all kinds of buried feelings about you and your own siblings, if you have them. It asserts that we act as our birth order for our entire lives. So if, for instance, you are the "responsible older child," you will be that in all aspects of your life forever if you aren't careful. Sometimes this is good and sometimes it isn't. The book forced me to think a lot about my relationship with my sister and it surprisingly made me appreciate her more than I usually do.
