When I talked to one of the breast feeding counsellors at my maternity hosptial (she's one of the midwives at the Queen Mum's in Glasgow), she said that so much of bf came down to early examples and almost needed to be started/encouraged (not literally!) at school. The "problem" with the bf workshops etc (and I went to one too and found it very useful) is that only those who are already interested in bf will go along. BUT they do have a positive effect in that the more people that are seen bf, then the more the "trickle down" effect will occur. (Personally, I hope I have encouraged my cousin's girlfriend to bf, should they ever get it together!)
There was(/is!) a bf support group that met every week in the maternity hospital - so I actually went along for the first time when ds was only a few days old and I was still an in-patient! (he'd had jaundice so I was in a wee bit longer than usual while he underwent phototherapy). What was good about it was that you knew where it was and could get into the routine very easily - as opposed to having to hunt around ONCE you'd hit problems.
Support in the very early days is very important - the midwives in the hospital had to spend ages with me helping to get ds latched on. With one exception, they all did so with good grace and patience.
The Queen Mum's is a UNICEF "Baby Friendly" hospital, so they didn't have any formula made up, although would make it up on request.
Glasgow also has a dreadul record in bf, so they have to work really hard for only a modicum of success. The amount of bf is still heavily postcode related (ie it's a "middle class" thing). They are working hard to try to change that. (Unfortunately, I only contribute to the middle class statistics!)
