I think there's some good advice here and some of the trainings do look they would work. As is always the case though each baby and family are unique so following the training perfectly will be almost impossible for most people. I plan to take parts from this book along with other advice from other books where they compliment or reinforce each other. One major issue with this book is that it's much harder to execute the plan if you are exclusively breast feeding. Whilst there are workarounds in the book for managing without formula or bottle feeding it's clearly not the approach the author would like you to take and means some of the steps won't work very well.
