Some useful info regarding stages (but timing didn't line up with my twins.) There's no true step-by-step... The "steps" are more informational vice instructive. The troubleshooting is more about breastfeeding and potential obstacles (with no resolutions) than actual troubleshooting. It's an ok book, but is geared toward the person learning about sleep training rather than the one in the throes of it trying to figure out a method. It's as if they wrote a book and then titled the sections based on what you'd love to know vice what the sections actually contained. Blah.
