My response? Never heard of it, and neither has M. In fact, M is one of four siblings, and I can't think of any example in M's family or social circle of a Pakistani family with less than three children (except those of us who are still in the babymaking stage of our lives.) Even the few families I know who belong to the very rich, higher class strata of Pakistani society still have more than 2 kids.
(Of course, I know there are plenty of Pakistani families with less than three kids - I'm just saying that *I* personally don't know any, which is true.)
So is this something any of you have heard about? Is it new? No amount of googling has produced anything. Is it hogwash?
