This book desperately needs to be updated. The out-of-date information on breastfeeding alone was enough to put me off (eg, that breast feeding has not been proven to be useful immunologically, etc). I did learn some new techniques my baby uses to self-soothe (sucking fists, etc) and I am relying on the pacifier a lot less, but overall the book was a big disappointment. I can't believe T Berry Brazelton has his name on this! Really just another person in the cry it out camp.
