Hi,Laura Carroll, author of Families of Two here. Of course I can recommend mine ;) if you are interested in happily married couples without children by choice. If the childfree decision has not been totally made, I love "I'm OK You're a Brat" -- it does a good job of realistically laying out whether you want o be a parent or not (or are ready) and treats the kid decision equally. Ellen Walker's recent Complete Without Kids is a decent read, as hers is part memoir, and part stories from others. She herself went down the path from child"less" to child"free" herself, which tends not to be talked about as much. Just a few ideas! I will be launching a book review site soon with a childfree section -- will post here when the site is up!
