A wonderful gift for a first-time expectant mother, the Mayo Clinic Guide to a Healthy Pregnancy is a reassuring reference on what to expect in pregnancy. Arranged in a month-by-month format, the guide describes the baby's growth at each stage and explains how the mother is changing, as well, both physically and emotionally. It's nice to be warned, for example, that at 17 to 20 weeks, mothers may experience dizziness, shortness of breath, heartburn and urinary tract infections. The book also offers decision guides on topics such as breastfeeding and circumcision and a reference section with common concerns of pregnancy arranged alphabetically. Authoritative, readable and well illustrated, this is an excellent addition to the already ample literature on pregnancy.
