Healthy Sleep Habits Happy Child by Dr. marc Weissbluth, this book saved my life when it cam to sleeping. My son has been a good sleeper since he was 8 months becasue of the book, i mean there are bumps along the way but for the most part it helps you to understand why the sleep problem is happening and how to fix it. It addresses the issues that can arise when there are more that one child in the home too. It will help and i paid about 10 dollars on amazon.com
