I feel like part of the problem is some of these kid sims are designed as uh... kids. Instead of doing what I do and genetic-ing and designing them as teens and then aging them down.
So since they never hit the teen button they look cute as kids, but then holy moly on aging up. I always thought Elsa was cute tho- just needed a different hairstyle and some skin details.
You also see this with the Sigworth’s kid. I uh. Had to shrink her head by A LOT. The problem is she didn’t even look like her parents!
