Rowlers - I can see your point and you may be right.
I'm def very middle class and didn't bf but my mum didn't either so you may have a point there. In fact, when I was struggling to bf ds1 my Mum didn't encourage me to carry on, she encouraged me to bottle feed because she did and all 3 of her kids are perfectly healthy! And of course I was having a terrible time, in tears at each feed and really getting quite depressed.
The class thing could also go along with the hypothesis I presented early in that older mothers may have had a career first and I think that they often tackle motherhood in the same way they did work - they strive for perfection and to do absolutely the right thing so it's often 'older' mothers that really strive for the bf, purely organic food, real nappies, lots of structured activities for pre-schoolers to make sure they can do a lot of things before they get to school.
I'm a bit stuck in the middle because I'm very middle class and hold some of those views and I'm surrounded by others who are also professional, middle class who get quite into the things I listed above. OTH, I've got my Mum very close by and she had us young (started at 21) and has a more 'down to earth' view on things I think so I end up going along the lines of the middle classes and my friends for some things, and others I just don't get stressed about because I can see that the way my mother did things still resulted in 3 healthy, intelligent adults.
I'm not offended by your comment because as a generalisation I think you could be right but, as always with generalisations, not everyone fits into it.
