All your sleep questions are answered in the book and if you read cover to cover. Mine is dog-eared and highlighted at this stage but I think you have to read every section and try every suggestion for at least a few weeks. from my experience there is no magic bullet…all the small tweaks suggested eventually bring results. I was up every hour with my new-born. Within 7 days of following ALL tips religiously (you can’t be a la carte) my baby now sleeps from 650pm-6am and only requires one feed max (sometimes he skips it). You need determination and loads of patience but worth it.
