Book Review: Families of Two

This is the title of a book by Laura Carroll with photos by Krista Bartz. It very simply presents the lives of 15 couples who are happily married and without children -- by choice. The same dozen or so questions were asked of each couple. The paths leading them to the same lifestyle choice are diverse, but the adjectives they use to describe their coupledom echo throughout the book. Here is a link to the author's related page: Families of Two.

Do Purple Women^TM experience greater relationship satisfaction than couples whose lives are focused on children? If both partners are cheerfully childfree, I would guess -- yes.
