I have read the 2 baby wise books and the child wise book. It seems a bit "strict" especially in today's permissive society. I just adjusted the things that seemed too extreme. I didn't really use any kind of isolation techniques or anything--that just seemed dumb. The books teach about sign language which I also did not utilise because I just felt lazy, but the concept is good. It teaches you how to teach your baby (in the high chair) early table manners, such as keeping hands out of hair, not dropping food on purpose, which I saw no harm in. I did find the breastfeeding instruction very helpful for myself and my infant son. Whereas many people are disturbed at the notion of scheduling a newborn's feedings I found that scheduling was the best thing I could do for him. The books state that so many mothers automatically put the baby to the breast the second he shows any sign of distress. (I did that). When in actuality there are countless other things the baby might need but of course does not know how to verbalise. If you just gave your baby a full 30 minute feeding and he's still crying chances are, he's not hungry but wants something else. It's mom and dad's job to figure out what it is. This concept seems so simple and duhhh. But I was one of those moms who believed that breast was the only way to comfort a fussy baby, and it took the Childwise book for me to figure out that was not the right thing to do. Plus it drastically reduced his spitting up.
