I would tend to assume that in cultures where the birth rate is sufficiently high, breastfeeding is sufficiently common and where such matters are handled more openly than is typical in the US, you would be less likely to hear people expressing bafflement as to why this seems to be so hard for some/many women when it seems like it ought to be "natural". My only point is that one of the differences between humans and animals is that some human cultures treat this in a rather secretive manner and we wear clothes and such.

I breastfed publicly in my twenties. I believe I was discreet about it but people who knew me well seemed to be shocked by how casually I handled it. Since they couldn't tell I was doing so until I told them I was feeding my kid while walking around the store or sitting in a booth at an eatery, I didn't see what the problem was. To most folks, I appeared to be holding a baby in my arms wrapped in a baby blanket -- which I was. He just also happened to be getting a meal. So I know first-hand how gasp-worthy this is to some folks, even if you are being so discreet about it they didn't realize it was happening until it came up in conversation. (And I was in Germany on an American military post for some of it. It wasn't all in the U.S. or only around Americans.)
