I was surprised to see so many people didn't like this book. I loved it and found a lot of the stuff worked for me. I couldn't bear the thought of controlled crying so I found the pick up put down to be really helpful. But as with everything I read, I take what I need from the book and discard what I don't find usedful. As for what she said about the colic, I must have skipped that part cause I don't remember seeing it.
