How would you handle this?

With the 8million kids it seems like live at my house, lol, I just tell them point blank that "we don't name call". If it happens again, I ask how they would feel if they were called _______ and that if they are angry that should say "I'm so mad at you" instead.

Of course, it still happens... and I still correct them... and one day they will realize that they love each other.
