A pregnancy only lasts for three days, whether you're playing the household or not. My suggestion is, if you're wishing to play a rotation, give yourself a full seven Sim days per household. That way you can plan the pregnancy to end before you have to switch households. I cannot stand some of the names the game will give the child if I'm not playing said household at the time of birth. One time it gave the baby boy the name of Hobert. No offence meant if anyone here bears that name, but it's just not one I have ever heard of prior, nor one I care for. :open_mouth: I don't play with vampires, so I know virtually nothing about them in this game. But, unless you use the MCCC mod, which allows for a pregnant woman to age during her pregnancy, she will not age a day, despite her pregnancy advancing. I do wish we could stop the NPCs/Townies from aging. In order for my families to keep their birth order (five siblings, in all) I have aging on for all. But, my Global Superstar keeps losing Paparazzi, whom he has befriended, and then he's horribly sad so very often. Now, anytime an Elder Paparazzi hangs around outside of Erik's estate, I use MCCC to age them down to Adult, trying to flatten that curve, you know?
So, what did I get the last time I played? A fan collapsed during Erik's concert and not because she was overwhelmed at seeing him perform in person, but because they were in Oasis Springs and it was HOT. Oi! My bad, I placed him there, trying to avoid the endless rain in the other neighborhoods. :'( Can't win for losing, sometimes …
