"Eat" "Eat" "Eat"

When Caden is ready to eat, he is ready at that moment. He grabs a Sponge Bob paper plate (no, I don't feed my kids on paper plates...they are left over from their birthday cake) and gets in his chair. He doesn't sit in his chair. He stand up on the ARMS of the booster seat and yells "eat, eat, eat" over and over again. He'll even start to jump and laugh when he falls. When he's done eating, he does the same thing. He doesn't yell anything though....he only does it because it makes Cam laugh and he LIKES IT when I yell at him. What is wrong with my children?????
