If you’ve ever been pregnant, or been close to someone who is pregnant, you know how many prohibitions there are. You can’t smoke or drink. Shellfish are to be avoided. In my house, conveniently (for the pregnant woman), scooping the cat litter was absolutely out of the question. Of course, there are also a large number of things you have to do when you are pregnant or are thinking of getting pregnant, like take folic acid.
Is there any evidence to support all these pregnancy rules? My good friend and colleague Emily Oster (whose research has been featured in SuperFreakonomics and many times on the blog), has just written the definitive book on the subject, entitled Expecting Better: Why the Conventional Pregnancy Wisdom Is Wrong-and What You Really Need to Know. She has generously agreed to answer blog reader questions, so fire away in the comments section below and, as always, we'll post her answers in good time!
