I noticed on my day off I go into my game first thing in the morning and when the mom had a baby the night before the kid is 3 years old. Thats after say 11 to 12 hours. When I had a mom with a baby and not played my game for say 24 hours and I play and find the kid is age 3. So I think that it does not matter how long you leave the game as I beleave that game is created to slow right down. So I beleave LDW have done a great job in case of emegenceis IE computer break downs etc. So als well that ends well

PS Oh another thing the more often you play the game the faster they grow older like if one player decideds to play every few hour, during the day time, say morning then noon then evening. They will have aged slightly faster than you would if played every 24 hours. I only play my game once a day now and the family live a lot longer age slower. Now that I know what happens after reading this post I might play it every 48 hours but I make sure they got lots of food first and all healthy.
