Query: It worked for us.

I wish we had received this book before our daughter was born. We fought the sleep/eating thing for quite a while. After hearing about this book from a friend that had tryed it, we gave it a shot. Man what a difference. It was tough to stick to it the first few nights. But looking back, it was much less stressful than the nights of endless attempts to stop the crying. It didn't take but a few nights to start to see improvement. After 7-10 days, she was sleeping through the night.
