Gail, don't throw the books out yet, even if you don't opt to persevere with the routines you'll find them really useful when it comes to weaning etc when baby is a bit older.
BUT IME it was worth persevering with the BW's advice - my babies were really SOOOO settled and happy when they had structure and regular sleeps. Both mine slept through from 7-7 from 3 months on the BW routine, and followed with really good napping routines throughout babyhood/toddlerhood. From what I read on here, those who tell you to 'go with the flow' seem to also to have sleep issues later down the track (Judgemental alert!)
If you're an 'academic' type it will probably suit you to a tee to have some structure in your day too.
BW isn't perfect though. e.g. She advises a 4 hour routine for babies older than 4 months old. While I followed BW I've found with my two kids that 3.5 hours at 4 months is far more realistic. At one month old, aim for spacing feeds at 2.5 hours - 3 hours.
At one month, the way to transition to a routine is to always begin your routine at the same time every day, say 7am. Always start at 7, whether baby fed last fed at 5am or 3am or midnight. That way the pattern will begin to emerge by itself.
Another way to transition is to gently wake (or rouse) your baby from daytime sleeps after 1.5 hours. No more than 2 hours at a time. Otherwise, day time sleep will rob night sleep. Rouse baby by taking off their blanket or opening the curtains and making 'daytime' noises around their cot.
HTH.
