Overall, this is not a book I would recommend to anyone to read. If you have a baby who has colic and you need ideas on how to soothe him, the book might be of use to you. As many readers have told me, the 5 S's can really help. I have said it many times and will say it again, if you are only interested in the 5 S's, you might prefer the DVD.
I have started to read The Baby Whisperer Solves All Your Problems, and there have been a couple of statements by Hogg that have stood out to me in light of this book. One thing found in chapter one is that Hogg briefly mentions mimicking the womb for baby, but describes the womb differently. She describes it as dark and quiet, which is different from Karp. She does, however, advocate swaddling in order to mimick the womb.
Hogg also says, "We know, for example, babies of depressed mothers tend to cry more themselves" (page 32). This is something Karp states as not being true. I tend to agree with Hogg. The saying, "If Mama ain't happyn, ain't nobody happy" is a saying for a reason. Mom really sets the tone for the mood in the home.
If your baby is a Babywise baby and does not have colic or extreme fussiness, I doubt you would find any enjoyment from this book.
