Hi WinterRose. The answer to your 2nd question is that the little people age the same game off as they do game on, 1 year approximately every 4 hours (after the age of 2).

As to why your other 4 family members are not aging, I could really use more information. Were your family members aging normally when you first started the game? When did you notice they'd stopped aging? Could something have happened that changed the clock settings on your device?
