My, this oneshot caused quite the 'uproar', huh? Anyway, at first I wasn't sure how I felt about this either - I was expecting drama or some kind of difficulties, but I wasn't expecting THAT - but after giving it some thought, I realized that maybe the point of this is simpler than what I expected: it doesn't really matter what happens 'behind the scenes', these two women find true happiness in being together with their children. That's it.
Though I might just be plain wrong :P
