Sue - I didn't read the other posts extensively and I am not weighing into any debates. I used the this book when I had my first baby. Like all parenting "how to" books you have to take only the advice that suits you or rings true. I used some of the ideas and not others. My first child was born loving routine so I found she suited having a set pattern to her day. My second and third babies were completely different and I found I just couldn't fit them into the suggested time slots etc. But I still used/use the sleep association advice. What I've found that eventually a baby will get themselves into a rough routine eventually.

all the best
