May I chime in?
Yes, kellymom.com has tons of excellent info and it is AP oriented, true. But breastfeeding has its own dynamics that differs from bottle feeding dynamics. Breastfeeding is naturally "designed" to be more attachment oriented, if you know what I mean :wink:. In my opinion, breastfeeding needs to be more flexible regarding schedules and such in order to succeed.
As for the number of breastfeeds per day, I think it really depends on mom, how she is planning weaning and when. If weaning is not in near futrure, there is no need to cut on feeds. If you plan to wean, just make sure your baby is getting minimum required amount of milk per day, doesn't matter how many feeds but matters the amount. I think you are right, at age of 1 year, 600 ml is a good amount.
