Interesting thread
There's certainly a respectable position that to make something Big Deal and Special about breastfeeding is not good - it sort of sidelines it, makes it fringey and like you say, not normal.
I also think that people who use formula do need to know more about how to do it - there are ways to formula feed that reduce its many risks and drawbacks, and of course mothers should know about them. But the most effective way to pass these ideas on is probably one to one, when the baby is actually here, and now I come to think about it, this is the most effective way to pass on breastfeeding skills!
I am an NCT breastfeeding counsellor and I do lead breastfeeding classes, 'cos they are part and parcel of the NCT antenatal course. On the whole, parents to be want to have a session on breastfeeding, and not to have one would be seen as a lesser service.
So we are prob stuck with the idea of doing a class on bf antenatally, a model which is also adopted in other a/n classes run by others.
But the most effective teaching I do on breastfeeding is, I think, afterwards, when the baby is real.
