Good Night, Sleep Tight

The other day I was talking to a friend and she recommended a book to me, as I was telling her about how "W" wasn't the greatest sleeper and that I couldn't make myself let him "cry it out". I can't remember the name of the book that she said was so wonderful, but while searching, I came across these. I think I might purchase one, or both. Anyone read either of them? Or tried them for that matter? PS, he goes to sleep fine, he just wakes up a lot in the night to eat and then goes right back to sleep.
