Query: A True Lifechanger...

I cannot praise this book enough. I had no help and was doing it all wrong for 3 months, setting myself up for failure. I was letting my child sleep in a swing all day and with a feeding at night. If I had not read this book right at the 3 month mark, I would have been in for a world of hurt. My son did not know how to put himself to sleep, something I didn't even know should be done. The EASY system that she describes is the best way to raise your child without using harsh, "cry-it-out" tactics. I love her and her book, and will be forever grateful.
