My Sim was married to evil Count Snypes, and when she got pregnant the first time, she had twin girls. She's a witch and he's a vampire, so they had one witch baby and one vampire baby. I didn't do anything to force the twins...just ate watermelon because she wanted a girl. Jump forward several years, the twins are teens, Sim is re-married (Count Snypes was just too evil) and she wanted another baby with her new husband, (he's her soul mate), well guess what??? Twins again!!! 2 girls, a witch baby and a human baby!!! Didn't do anything to force the twins or the gender.
What are the chances of this? Is it because she had "mixed marriages"? Its not a problem, I just was very surprised...both times!!
Thanks,
Allie
