I wasn't but I think my son is! We've been working with him to talk through appropriate class behavior and it's made a huge difference.
I realized though, that I don't know much about how to make a class clown happy (outside of letting him say whatever he wants in class, whenever he wants). What kind of alternate outlets can we give him to get that energy out?
Were you a class clown? I'd love to hear one thing that worked for you as a kid!
