Ah, I hate to go against the flow but we've been following BW. This book stresses the importance of being flexible a lot so unless you ignore that, then of course this book sounds awful. Caty, by the way, is the most content little creature.
A lot of people I know have used it (hence us checking it out) and their kids are fine....I would imagine (and hope) the majority of people who do BW are flexible with it, hence it 'works' for them.
Then again, I've had some who have used it for the first bubs with no probs, then with the second it wont suit at all....so I guess a lot of it is up who bubs is?
Anyway, whatever works I say. This works for me, wont work for you, and might work for the next person.

ps: ha, please don't hate me for this post!
