Question about the *spawning of children...

[Jamers]

So I know that children are chosen at random from a pool of possible children available to one's particular wife, and that they spawn 10 battles after discussing having a child.

BUT does anyone know if the child that is produced is chosen at the time of the 'discussion', or if it's randomly chosen immediately after that 10th battle?

Basically what I want to know is: if I don't like the child that's produced after the 10th battle, can I reload a save just before the battle, fight it again, and end up with a different kid? I got stuck with a couple crap children last time and I'd rather stick with equipment slots that have +4 scroll capacity or some garbage.

ALSO: does the slot that the child takes up also shift? Not only with reloads as mentioned above, but is there an order to the sequence with which the children fill up slots?

Thanks a lot in advance.
