Oh I see, well honestly mine was just out of curiosity, because I have never once had a bad pregnancy, though I've heard people trying to get them for another type of legacy challenge where they needed a "bad apple", and this made me curious as to how someone might do such a thing to end up with a bad pregnancy. Thank you for explaining, however I like picking my traits, I always plan ahead for the futures of my Sim children, and picking traits is always a plus when you already know what you're going for career/lifetime wish wise.
