Not offended at all, fanjo :) It's a shame you didn't get what you wanted from the class. It's certainly the case that while bf problems are common, for all sorts of reasons, reading a talkboard skews things - and often, as we see here, a lot of problems are actually caused by people not understanding how things work. Think of the threads which describe perfectly normal bf behaviour ie a baby feeding in response to his needs and desires rather than to the clock....not a problem with bf, and not something that normally needs a supplement.
There is an educational benefit in men bonding with men - something they find easier in a same sex group. It does not matter a great deal if they stray off topic, really. Indeed, discussing myths is important. Men (we know) are far less likely to read books about bf, and are more likely to hear 'stuff' - a discussion on myths can help dispel some of what they hear.
The idea that we have to get the right parts of the nipple into the mouth is not exactly wrong, but a prescriptive set of instructions about how to breastfeed is, I would say, less common these days. It does not help - when we used to teach this, plenty of women were still very sore and damaged. Biological nurturing research has shown us that babies do a lot of the positioning and attachment 'work' themselves if left to it. Certainly, when I see a mother who is having difficulty with soreness and the baby doesn't get on 'right', I try BN with her and it works most times - she needs to forget all this stuff about lining up the baby and eliciting a gape and getting more of the areola in blah blah blah.
I can't remember when I last discussed a 'correct' latch - this sort of thing just perpetuates the idea that women can 'do it wrong' and makes it sound a fragile thing. I do explain that a deep latch makes effective feeding possible and comfortable and I say something of what is happening in the baby's mouth.
Babies attach themselves, if they're healthy and if they stay in close contact with their mothers and if their feeding cues are responded to. This doesn't have to be nekkid, skin to skin, BN all the time, either, though it does help if this is done a lot in the early days.
The bfc should not leave you with the impresh that it is bound to be trouble free for all of you. But a major part of her class should indeed be on presenting normal breastfeeding.
You should be given a chance to evaluate the class and feedback your concerns to the bfc. I think we should probably explain better why we don't give a set of instructions, a list of creams and a roll call of all the problems - you've made me think, and at my next class I will tell them why I won't do it like that :)
