Do you give your Sim children plastic surgery if they don't look pretty enough for you?

I do edit their looks, but it's not to make them prettier, it's more to make them the way I need them to for a certain character as most of my Sims are based around characters from stories I've written and I want them to look how I've described them in the story. Sometimes that is "Prettier" but just as often it's not.

(If it's not a game born "character" but just a random child Sim that I hadn't pictured first I usually only edit hair style and clothing)
