The interesting result of the take the baby away somewhere more private when it's hungry stance is how it neatly links back to (as you talked about) the false equivalence of breast milk and shit and urine. If away from home, the breastfeeding mother, if she can go anywhere, gets to head off to the loos where, if there is a separate baby changing facility (and not simply an albeit handy pull-down "workstation" in the Ladies) she can sit alongside the bag of baby waste and a possibly not clean changing table on an uncomfortable chair if there is one and on the toilet if not. See milk and piss are equally bad and must be hidden. This of course means that for the next period of time (an hour say) you make the loo and changing facilities unavailable for anyone else--more disruption elsewhere as damp babies are unhappy babies. And you get to sit surrounded by the smell of urine and shit.

On one occasion, the baby changing was in the disabled loo (nope, I don't mean that, I mean the functioning loo for those with mobility problems). Obviously, as well as being disgusting, breastfeeding's a disability. I used that one (for a change rather than a feed) with as much speed as I could since those with restricted movement or a wheelchair shouldn't have to be incommoded (pun was inadvertent, but I'll let it stand) any more than they already are by being forced to share like that.
