You can't delete the sim in the Sims Mobile but when they are an adult you can move them out or promote them so you can change their appearance.

You are not able to change what your kid looks like, let's just pretend it had cancer :P. But on the real note I think you should just uninstall your sims and then install it to restart. I know its a pain to re-do it, (I've done it 2 times) but I think it is worth it if you don't like how she looks.
