I bought this book as part of my research for my pregnancy yoga class that I teach. I particularly liked the relaxations in the book. Would recommend this book to anyone either a teacher or someone pregnant looking to practice on their own.
I used this book for most of my pregnancy, it said not to do any yoga for the first trimester. The style is simple to follow and thorough with clear photographs to show you the positions. The only down side is having to keep referring to the book when starting out, though that would be with any book, it would be nice to have had a dvd version of this book in particular.
