Just that really. I read a couple of pregnancy books during the first few weeks and was really disappointed by them (found much of the info a bit fluffy or obvious, e.g. eat five fruit and veg a day and do gentle exercise).
This will be my first baby so I do feel like I should be reading something but I also feel, perhaps very naively, like a lot of things should be instinctive.
Given experience with the pregnancy books I suspect I'm probably more interested in science/developmental based books, though am mainly interested in which books other women actually found genuinely useful!
