My all time favourite: Baby Wisdom by Deborah Jackson (not just about babies, but about how different societies "do" babies)
Others I'd recommend: Anything else by DJ, Naomi Stadlen (what mothers do...) Continuum Concept......Kaz Cooke,(for the belly laughs)
Ones I have dipped into when the time has been right: Sears (although very sugary sacchariney sweet and IMO might possibly tip children over the edge as there is a fine line between being an attachement parent and being a doormat....)
Funny stuff: Mel Giedroyc's ones, Fish Finger Years woman.....
Ones I have read and now wouldn't wipe my arse on in an emergency: GF, TH, Miriam bonkers Stoppard, Fat Ladies Club (any MN could have written this, but it would have been better....just because you're having a fecking baby doesn't turn you into a writer)
