I'm in the UK but i've ONLY read good things about the ABA book so i'd definitely second that - it seems from so many threads on here that joining ABA is the best money a lot of pregnant and new mums have ever spent!

My own personal fave is "breastfeeding your baby" by Sheila Kitzinger (i've just seen it on amazon for 56pence!). It's full of photos and concise, useful information. It's not "everything you need to know" like a BFing class/group would be, but it's so handy for reminding yourself of concepts and a LIFESAVER for those middle of the night moments when something is up and you think "oh crumbs, what now?". Also it has lovely photos whch if nothing else made me very gooey about BFing and thus more determined to do it
