There is a new book out this week on pregnancy, called 'Expecting Better: why the conventional pregnancy wisdom is wrong and what you really need to know'. I pre-ordered a few days ago, and it arrived on Friday. There's a profile of the book on the BBC site here:

The author is Emily Oster, an economics professor from the University of Chicago. I first heard about her on the Radio 4 programme 'More or Less', when someone was describing this book. She starts with the idea that in order to make sensible decisions about what to do and not to do when pregnant, you need information on the risks, combined with your personal information about what the pros and cons are.
So far I'm halfway through, and I think it's excellent. It's well written, and with a sense of humour as well as an analytical mind. It probably helps that I have a bit of an analytical background myself, and work with economists, but I think the language is easily understandable.
She seems to have received most attention for her chapter on caffeine and alcohol, where she tries to separate out the risks of heavy consumption (bad in both cases) from the risks of low but not zero consumption. For instance, I had no idea that although caffeine consumption is linked to miscarriage, women who are nauseous are less likely to be drinking coffee, and nausea is a symptom that means you are less likely to miscarry. So it's possible (at least at low levels) that the women drinking coffee are just less likely to be the ones feeling sick.
I really appreciate someone explaining what is going on, and what the evidence is for why you should do something - it makes much more sense to me than a simple rule that applies to everyone, when everyone is different.
I would love to know what other MNers think.
