Yes but what I am saying is that if you have no experience whatsoever you go with what is recommended to you otherwise going into waterstones and trying to choose one is pretty bloody scary, so you might choose one that your friends have chosen to read and found useful - especially pre birth.
Equally now I know what to read and what not to bother - within each book, some have great advice and some interesting 
ways of doing things but if you use it as a pointer then things can be great.
Interestingly am not sticking up for CBC or any of them, read the cbc book prior to dd (3) birth, thought it was quite useful but i also went to the nct bf councellor. Luckily I found bf to be pretty easy, thought I would read it prior to ds (5 months) I did think what a lot of bollocks . Infact the only thing I found vaguely useful was the picture of latching on 
.
Equally sometimes I turn to Gina and then run very fast in the other direction screaming, equally do the same for the baby whisperer.
Am I allowed to say am currently foraging through Annabel karmels 100 puree's & 100 finger foods to get some ideas for ds as am totally uninspired for some weaning ideas.
What scares me is my friend who uses GF like a bible and recommended cbc. (Didn't bf as her dh didn't like it 
) If she recommends a book to me I steer clear. Am now much more savvy and read all the reviews then double check on mn. However I am 3.5 years down the line now........and have found mn! (Accidentally btw - was looking for nm to find local "things to do" and discovered the jackpot instead ) All I am saying is be gentle on the innocent, just incase they are innocent!
