@Simmerville Oh my! And here I am overwhelmed by my 5 families. That sounds amazingly chaotic.
I think I'm going to play with my seasons at 28 days and my life span at 117 for a total life. I will turn aging on for 4 weeks right before it is time to switch families for everyone not played and then off when I switch families. Then depending on the none played I care about, either turn aging off or age then up if needed, but this way, by the time I make it back to my the first family all none played sims will have aged a full span.
