I bought this book based on the great reviews here, and the fact that my first child (daughter) is to be born in about a month.
I greatly appreciate the author's writing style --- helpful, not condescending, slightly humorous at times, personal, etc.
I would consider myself an intermediate photographer: been shooting with DSLRs for a few years, have studied various books/manuals on digital photography, frequently post process using GIMP. While I didn't really learn anything new in this book concerning camera settings (ISO, shutter, apeture) I really appreciate it as a refresher course on some things. Overall my favorite part of the book (and the reason I bought it) is the great example shots. They serve as a great jumping off point for shots I hope to get with my newborn.
I also really appreciate how the book is divided into months of life, making it a easy, logical read.
At $10 I highly recommend this book, and it even if you don't learn anything new from it it makes a wonderful coffee table book because who doesnt like great pictures of babies?!?!
