DCcopying swearing within the class

[airhostess]

Hello,
brought child up doing all the right things, DC exposed to child in their class that is violent and a potty mouth.
My DC in temper now swears the most awful words you can imagine.
Have met with school, nothing they can do, put up or leave. Obviously not told that but nothing they can do. Safeguarding in place blah, blah.

What on earth do I do? Devastated.

They all get exposed to swearing at some point or another. I really wouldn't worry about it. The worst thing you can do is to make a fuss, just quietly tell them not to say that word again and move on.
