To evolve from a kid to a teenager is defianantly not 12 hours. Its more like 2 or 3 days, depending on how much you pause it. OldSchoolTama, your right. Patience is a virtue.
I've read on many places before, on eveolve-lists that:Baby to toddler=1hour, and toddler to teen"rest of the day" I havent checked myself, but I think it is a lot less than 2 to 3 days... mine evoles really much faster anyway...
