What Would Happen if Adam and Eve Had Children Before They Fall?

What would happen if adam and eve had children before they fell? Of course, it's a matter of speculation. But since human nature had not been damaged before the fall, it would have been able to perform its original function that god intended us to be able to do. The kids might have had the ability to resist the fall. And so you've got fallen parents and unfallen children, which would be very interesting.
