I play a rotational style game. I currently have twelve households, and I rotate among them. Since I made the mistake of creating some of my sims as adults rather than young adults, I currently have turned aging completely off. I'm going to see if it's possible to manually age my sims when I want.
The only real problem I've found in my gameplay is that sims do give birth before I want them to. I'm hoping maybe there will be a way to "tweak" the length of time a sim remains pregnant. I have an "in-game" calendar that's part of my play style. So, I "pretend" it's January when I'm playing Sim A's household, then when I move to Sim B's household, it's "February"...and so on. Thus, if Sim A gets pregnant in January, I want to go back to that household 9 "months" later when my in-game rotation tells me it's October, and I want her to then have the baby. As it is now, the babies are born way ahead of my game schedule. I just have to live with it for now, but I've asked in the mods forum if there might be a way to adjust this.
Other than that, the rotational style is working well for me. My sims will go out, meet people, and make friends while I'm playing other households, but thank goodness, they don't have career promotions, change jobs, or conceive children on their own.
Good luck with your game play. I hope it works out for you and your sims, too.
