This is a hard one for me, since I didn't have too many problems and had access to an abundance of education, etc.

I chose Going back to work with a lack of bf support. I think many of the comments on here relate to why women don't bf soon after the birth, in the first few months, which I think is hard pin down (society?). But from the figures I've read, Australia also has a shocking record of bfing to 6 mths and as for getting to 12 mths...! IMO the reason for that is that so many Mums have to go back to work. There aren't a lot of expressing facilities in most workplaces, it's considered a bit 'odd' and childcare centres don't seem to be geared around using expressed bm. While I didn't have to go back to work, since I work from home, I had to organise times to be at clients' offices around Lucy's feeding times (certainly can't whip out a pump in the middle of a meeting!), and OMG that's a challenge! In countries where there is paid maternity leave the bf rate is much higher.

My second choice would be a lack of good education. Some of the stories I've heard from others and what they've been told (by health professionals, which is scary) is totally contradictory to what I read from reliable sources and found to be true.
