As a counter opinion, I hope that if there is a pregnancy feature added, it's strictly optional. There are games where I feel that adds to the game, but I don't believe this is one of them. This game is more like trying to retain your sanity while the game slowly(or not so slowly) centers on victimizing you. If anything, it would be more fitting for Bailey to either force an abortion(which may be bordering on a bridge too far even for this game) or to take the baby away and sell it(also a pretty awful choice, but somehow less so for being less realistic).
Either way, adding childcare of all things as a management mechanic would, in my opinion, take too much focus away from the main themes of the game and threaten to make it a general life sim, which are (again, my opinion) dreadfully boring.
