I was just pondering - what do you think is the point, narratively speaking, of Aviendha's babies? We were told they'll be quadruplets, and in ToM we learn they're born channeling - very odd, when channeling ability doesn't normally manifest until well into puberty. But why? The chances of a woman in a preindustrial society even managing to carry four children to term, never mind any of them surviving, are staggeringly low. Their channeling is entirely unprecedented, so far as we know. But nothing I read of them in ToM required four siblings, or even, really, that they be channelers at all.

I doubt it was put in as some sort of gimmick. Jordan must have had a reason for including such an astonishingly unlikely event, but I can't see us finding out what it was.
