A book I would recommend for pregnancy is the The Mama Natural Week-by-Week Guide to Pregnancy and Childbirth, and I would recommend this book for all healthy tips during pregnancy. I love how the describe what is happening for baby each week and what you can do each week to help create the healthiest baby possible. I love natural solutions to problems, and this mama has provided a complete handbook full of information. I wish this book was out when I was pregnant. I followed this Mama Natural website and blog during my pregnancy, and I would have devoured this book when I was pregnant. I love it so much I bought it after I already had my baby. Genevieve Howland has put all the information you want to find into one handbook.
