I can't remember ever changing children.. not because they are pretty or not but because they usually look pretty much the same.. except for skin, hair color ect. I actually like it if their features are different than the norm. I'm sure if they came out in a way that didn't fit my story though I would without hesitation. Like if I needed a red headed child for example.
I sometimes change teenagers because that's when the problems show up for me. I often play male and female caricatures and the genetic mix is often pretty bad. If the father is a slim hipped, jutting jaw, hooked nosed, barrel chested brute and he marries a perky nosed, heart shaped face, voluptuous woman the chance of their teens turning out somewhat symmetrical is pretty close to zero. Sometimes though they are still left as is also, it just depends on what's going on in the game... it's really not about pretty. It's about the story.
