More ages for sims

Of course, this isn't needed at all but I think it'd be pretty sweet if we had more than just baby, infant, toddler, kid, teen, young adult, adult, and elder. In between kid and teen would be pre-teen and in between toddler and kid would be little kid. I personally think these two would be cool, but it would make playing the game slightly more annoying because aging up would take WAYYY longer than necessary for the regular Sims 4 life. What do you guys think?
