Query: A truly outstanding breastfeeding guide

I purchased this book while researching the breastfeeding chapter in one of my forthcoming books. I immediately fell in love with this book -- specifically, with its innovative approach to the material (the seven natural laws) and its warm, supportive, and mother-friendly tone. The authors do a terrific job of explaining the root causes of many common breastfeeding problems in ways that make so much sense. Their section on how taking a "left-brained" approach to the very "right-brained" act of breastfeeding is totally brilliant. I can't praise this book highly enough.
