Sorry for the necromancy everyone, I would've responded earlier, but had to work.

That's the latter statement to which we were still under the guise of the child being Ogb, so that means moot in your defence.If you had corrected my former statement and said you were talking about the normal child then things might've turned out different. I can quote it if you like, no trouble at all 
The child has to be conceived before the Old God's Soul can do ???????(IIRC, it still isn't known with certainty if the souls merged or whatever.). So, since the child must be conceived before, Wardens can have children.
Of course but the Argument was how does it break my Rp and since the Rp I stated Involved Alistair, having no Alistair...well I'm sure you follow.
How does the PC know that Alistair and her can't have children? There is no in-game declaration of it(only evidence that it would be very difficult). Regardless, it is impossible to provide every option(especially post-story) in a CRPG. Just as my Warden can't be bitten by a radioactive spider and proceed to fight crime in New York after DAO, your Warden can't have kids with Alistair. If it upsets you that much, just headcanon it. It is highly doubtful we will see the Warden again anyway in future DA games.
