Correct and natural as is?

Hi teachers, could you please check if this dialogue is correct and natural as is?

"Stop using those kind of words around my daughter."

"She better get used to it."

"Get used to what?"

"Hearing swear words. She's starting school next week, and other kids curse, so why not prepare her? I know you're a priest and that's affected her, but I think we need to learn her that it's not a sin to curse and that she shouldn't judge other people over it."
