The Sims 4

So I know that recently there was an update so that you can do more interactions with infants and stuff, my question is tho when are we getting a pre-teen age group thing? the jump from kid to teenager is just really weird to me cuz they go from being like 4 feet tall to looking like how they do for the rest of their sim life pretty much. Ik a lot of people have said something about it but its just on my mind rn
