Another good book is “Nighttime Parenting” by Dr. William Sears.
Nighttime Parenting is the book that will help you really help your baby to sleep better, not "train" her. It is for parents who are willing to have patience with their babies, and not try to force them into rigid patterns before they are ready. It was a book that really helped me when my eldest child was about a year old and constantly waking at night. I knew that I couldn't let my baby cry herself to sleep as so many other books and people recommend. When it comes down to really helping your baby takes time, and effort. It's not easy, but did we really choose to become parents because we thought it would be easy? After using the suggestions in this book, my baby did start to sleep for longer stretches than she was and not at the expense of her trust and our relationship.
Dr. Sears also has a great web site,
