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

I usually have an idea of how I want my sims to look, so I will play with genetics in CAS until I'm happy with the result. I will only change the body shape and hair and eye colour if needed as I like to keep the genetics (unless it is an adopted baby - then anything goes). If I want to play the baby stage I then use MCCC to copy/paste the sim I made in CAS onto the baby once it ages up to a toddler.
