Cursing is a natural thing for kids to try out especially school-age children. If you hear your toddler using a word that you don't like, just try to not use it yourself. If it is a repetitive thing then you can just let them know that that is not a good word and mommy and daddy shouldn't be using it either.
For an older kid, your response should probably match their intentions so it should never be tolerated if a kid is swearing and using bad words towards another person in a hurtful way. If it is in a moment of frustration where they got hurt or something happened that upset them, you can be a little bit more understanding and just remind them that those are not words that we prefer.
