This book was very helpful to me when I was pregnant. This is a rare topic. I used the information in this book to help me during my pregnancy including for use during birth and to help start off labor! The book is packed with useful information, loads of details are in the book. The topics start at preconception, then go into pregnancy, before labor, during labor, postpartum and then care of babies, too. This book tells you how to safely use essential oils.
