Would you normally say "it's impolite [any continuation or no continuation at all]" or the word impolite is too formal for kids and you would rather choose to express the same thought in a different way?
The reason I asked this question is because the other day I witnessed this scene: A mother (Asian) in a restaurant was correcting her child's behaviour saying, "Don't put your feet on the couch" when her child asked her why she was not allowing him to do so, she said, "because it's impolite." Her friend who was sitting next to her (obviously British, judging by his accent) said, "We wouldn't use the word impolite when talking to children, it's too formal."
It seems to me that I have heard some native English speakers (I don't remember whether they were Americans or British) use this word when talking to their children. On the other hand, that mother's friend didn't need to lie. So I decided to ask this question here.

I think impolite is the most polite word to use when you're pointing out or warning the kids against bad etiquettes or rude manners.
