Don't let the size of the book put you off - yes it looks like a weighty tome, but it's crammed full of useful information. If, like me, you wanted to know absolutely everything that can happen, this book is worth buying. It's not funny, there are no characterisations or diaries, but it is a good companion - even from before you conceive. I especially like the week by week development of the foetus - lots of books miss great chunks of this, but this covers it all and has photos etc too. I've kept referring to it most nights when I'm in bed! It doen't patronise - which as a health professional, I was grateful for -but it doesn't assume you know loads either, which was reassuring. As with any pregnancy book, reading too far ahead can scare you, so be careful. It does go into a lot of complications and problems - but in my opinion, forewarned is forearmed. I'd recommend this to anyone who wants to know a lot about what's going on inside them during pregnancy - and to those who want to get up to speed before conception. I wouldn't be without it.
