I think you're wise. The Phantom's deformity was laughably mild (Cleolinda referred to it as a bad sunburn), while Vader's little problem was played to the hilt, complete with screams of pain.

Also, in the future nobody gets prenatal care.

Speaking of which, this week my daughter (14) went to an assembly in which teen parents explained why teen parenthood was bad. They did this by telling horror stories about childbirth; she came home and was nervously asking questions about vaginal tearing. I did my best to talk her down. Bad enough when people tell these stories to pregnant adults...
