I'm a researching kind of person at the best of times and pregnancy has given me a lot of scope for investigation. I've had a fine time reading all kinds of books and websites. Here are the books I chose for home to be read and reread.
First, the practical books that give you all the information you need to discourse knowledgeably with your friends about fundal heights and lineas nigra, to frighten yourself about all the arcane ailments you and your baby can acquire, to understand the wonders of the baby's development week by week (my favorite sections), and to prepare yourself for the physical and emotional changes you go through during the pregnancy. They also give you more information than is quite comfortable about labour and childbirth!
