I feel like that would be a huge violation of the personal identity of the kid. I love my parents and I think they're better at most at being parents, but I don't trust them with certain things because of their personalities. Thinking about them having a choice on how I physically am by their whims is chilling imo. I'm their son, not their project or experiment. 

Edit: I never even liked them dressing me.

Forgot to ^ this though. People just never listen with the vaccines.
