Awesome, thanks so much elpgal! I'm not actually all that invested in the current dialogue about breastfeeding, so that page is a gold mine. (I mean, I breastfed both my kids because I made a lot of milk and it seemed like the sensible thing to do, at least for the first few months, but I wasn't a martyr about it).
To be honest, I was quite alarmed to discover the lengths women will go to breastfeed under adverse conditions, and also how freely some women shame other women for not breasfeeding! Why do women care what other mothers do? While it's true that breast milk is a little healthier than formula, it's not like formula is made of mashed bugs and arsenic. It's a perfectly good substitute if a woman can't, or doesn't want to, breastfeed. And why do we have to be so focused on providing the VERY VERY BEST OF EVERYTHING for our babies? Talk about pressure.
I also think it's interesting that on the one hand, we North Americans are "officially" pro-breastfeeding (breast is best, formula is evil, etc) but on the other hand, as a culture we seem so uncomfortable about the actual act -- especially if it involves toddlers. Popular culture shows this. After a quick read through of the comments on that Facebook page, I could see that most TV and movie scenes that involve breastfeeding (a) involve a newborn or young infant, and (b) are played for laughs.
