Any baby sleep training book to recommend? I prefer NO cry-it-out method.

How about the "Sleeping Like A Baby" by Pinky McKay. Not only is she a best-selling author, she is also a mother of 5. So she knows what she's talking about. Pinky does not only writes about knowledge and personal experience, she has science to back her up. She also includes other mothers' experience so reading this book is pretty holistic.
