There is a reason why teens in the game are the same height as adults. Adding a new height would require an expansion pack because of the programming required. I don't see many that would pay for this for very little gameplay. Braces and more freckles than we have can be added to child and teen
Preteen means before teen as in before thirteen. The child stage today is 14 days (standard) taking 5 days out of it would be too much. Besides you did not answer how you would depict a preteen.
But Teens Are In High School And 13 Year Olds Are Not In High School So Let's Just Add It Into The Preteen Stage. Or They Can Shorten It To 9 Or 10 Days For Children So 4-5 Then 6-8 And 9-13 And It Is Fixed.
