This book is optional for the course.
From back cover: The Official Lamaze Guide is the first and only pregnancy and childbirth guide endorsed by Lamaze International, the leading childbirth education organization in North America. Its goal is to take the mystery out of having a baby and help you better understand how your body works during pregnancy and childbirth, giving you the confidence to make decisions that best ensure the safety and health of you and your baby.
Hello! Quick check.. It seems like the 2010 publication of this book is the second edition. There is a 2017 publication of this book (and this seems to be the latest), with a different cover by the same author, that is listed as the 3rd edition.
The 2010 publication is no longer in print. If I were to purchase, is it okay to just go ahead with the 2017, 3rd edition? (If the 2010 publication is preferable, I can purchase it used.)
The 2017, 3rd Edition will be fine. The Lamaze Guide is not a required reading text for the program. It is listed here as suggested supplemental reading.
