Sacramento Book Review, June 2012"Has been a mainstay for both couples considering hiring a doula and women in training to become a doula for years...This book is a great place for women to start when looking to learn more about labor companions. It is full of valuable knowledge and useful personal anecdotes that pregnant women and potential doulas alike will find beneficial. Spread the word and hire a doula!" Portland Book Review, 9/12/12 "Clear, motivational, and inspirational."
