I had a female Sim get pregnant and I switched over to another household and when I returned the female Sim had given birth. I have auto-aging turned off and only aging is allowed in the active househ...
yep, if you make a autonomous sim pregnant or something make her pregnant, then the baby will born no matter you can do, but this dont means who their now can make babies by themselfs you still need to "help them", innactive dont means who the sim is completly frozen in time, somethings can happen, like pregnant womans give birth to babies or if you age is enabled, their age and even die of age, will be the only way for then die, if their dont die for something where you are at.
