Although this book is a bit dated, I still found it to be relevant.
Safer is a psychologist, so she thoroughly inspects the reason behind why women choose childlessness.
I felt that this book had a very forgiving tone and wasn't quick to judge women who become mothers, as a lot of these types of books can do.
Safer recognizes that choosing to not have children is something that women can miss out on, while still having fulfilling lives. She doesn't make it sound like a life without children is better than with, only different.
I truly appreciated that approach, as I am still on the cusp of choosing whether or not I want children and I do not want to see motherhood completely denigrated.
Recommended reading for women trying to decide on motherhood for themselves.
