Aging OFF Can sim get pregnant and what happens?

Thank you all so much for answering. :D

So with all aging off she can still get pregnant, go through normal pregnancy (3 days? I thnk), and have the baby in the bassinet.

But the baby will stay an infant forever.

And without any cheats or "boolprop", I can buy a cake to age the baby up if I want?

Edit: To age the infant to a child I click on it's crib, but don't need to enter any cheats?
