My favourite week by week pregnancy one is Kaz Cooke's "Up the Duff" or it's also published under The Rough Guide to Pregnancy depending on the edition and country. Just make sure you get the Kaz Cooke one - it's really funny, reassuring and down to earth.
The only sleep book I liked was The No Cry Sleep Solution. Generally any book which offers solutions which have special little names is to be avoided and thrown several feet into a river. Common sense advice, realistic expectations and lots of ideas of things to try are what helped me. I also loved Three In A Bed, but that one is about co sleeping so it's very specific and doesn't talk about any other sleep related things.
Breastfeeding, you can't go wrong with The Food of Love by Kate Evans, although you should definitely top this up with a large dose of the mumsnet breast and bottle feeding forums.
Why Love Matters is very well researched and sourced, too, and is really interesting but it's less "how to" and more "interesting".
Mine (the post birth ones anyway) are probably spilling over into attachmenty... I have to say though that attachment doesn't mean "being totally child led forever" and most AP type resources do encourage and give help/guidelines for introducing boundaries, respect etc as children grow up. It's a bit of a myth that AP is all about standing around saying "Oh no Camilla, darling, please don't bonk poor Archie on the head with the train track, that isn't very nice is it?" and not actually doing anything.
A non AP one - What Mothers Do (especially when it looks like nothing) by Naomi Stadlen should be required reading for every new mother. I strongly recommend buying a used copy on amazon and writing inside the cover "When your baby reaches 12 months, put this book away and then pass it on to the next woman you know who is expecting a baby." Pass it on and ask her to continue the chain. Amazing book.
