This book was not really what I wanted.  It's very much about childfree by choice - not childless not by choice - and the author, while claiming to be inclusive of people with infertility, had some pretty nasty things to say at times.  That being said, it had some good statistics and info from studies and things to think about.  I wouldn't read this as a first step to childlessness but once you've explored it awhile it might be worth it.  If you're childfree and comfortable with that then I think it's a great book even though it's 30 years old.
