Gretchen Nalley, the author, describes herself (in part) as a computer systems administrator and web designer. Then says: She wanted to share these exciting sites with other parents, help them save both time and money and, as much as possible, help make parenthood child's play.
I have not read the book, it could be great, but... what I want to know is: Why a book and not a website? You would think that a web designer believes in the Web, and would like to offer those links in clickable format. I know that would be closer to child's play for parents.
To be fair, they do have a few links in their page of updates. The links page doesn't count because it has very few, and they look like sponsors.
