This is not a comment on breastfeeding, it's an acknowledgement of the environment.
Living in the US.
Downvoters: Rebutal?
Some countries are better at dealing with this than others, but I don't think Europeans are perfect on the matter either.
>should they have be more discrete?
Like how? Do you want mothers to retreat to a disgusting public restroom to feed baby?
Most mothers that I've seen publically breastfeeding have a light cloth that they drape over themselves. Portable, cheap, and effective.
Do you want that to be law? It's what my wife usually did with our children. Our friends' child though, refused to feed under a cloth and would cry or thrash until the cloth was removed.
I was merely pointing out that "going to a disgusting bathroom" is far from the only concealment option.
