I'm a bit of a lurker.. and haven't read this post through but I just wanted to put my 2-cents in. I hope that I'm not too bold in saying this.

But other than the lack of knowledge and the publics view of public breastfeeding.. I think a huge part is how every tries to be PC... so as not to offend anyone we don't always push the benefits of breastfeeding. We *know* that Breast is Best but often when said in a group of mothers, we're met with scowls, or "you're only saying that because you can do it" etc. It sucks that, in our efforts to keep everyone happy, we have to keep quiet all the benefits because people who didn't breastfeed get upset.
Lest we remind people that breastfeeding is what the boobs were made for.
