Hi C.!
As a Mother of three grown boys, I know what you are going through. I raised them by myself, so I had many challenges. We had a "swear jar" Whenever my sons used an inappropriate word, (even Mom) we had to put a quarter in the jar. Start with what you think might be an appropriate amount. I would ask for their input too. If they are getting an allowance, I would start high! If that doesn't work, then up the anti to a dollar. When they start losing money real quick they learn very fast. You can decide what to do with the money. Either give it to charity or some family that might use it. Don't give it back to them. They have to feel the pain!! Hope that helps, it worked for me. Mother of 3 grown men,( I wish they were here and little again) and a young daughter!
