This book is written by two knowledgeable professionals, however, it is full of negative information regarding what can go wrong during your pregnancy and all the bad things that could affect your fetus. Granted, this is useful information for a small percentage of women who are pregnant, but I've pretty much stopped reading it (and will skim some parts only) because the material can really scare you and make you anxious. If you are a first-time Mom like myself, I'd choose a different, more positive book on pregnancy and enjoy the experience.
