Running around, being loud and making messes are not discipline-worthy UNLESS, you have told him to stop (not ALL the time, but when you need him to behave) and he refuses to do as you say. Then he could use more discipline. My kids have tons of freedom and play time, and I'm laid back in the house, but when the need to behave (meals, errands, library, company is over, it's time to settle down for the night, whatever) they are not allowed to be defiant when I tell them it's time to behave and quiet down, and they have to comply. Sometimes they can run and be wild in the house, sometimes they can't. Having him do "whatever you say" is the best way to allow the most freedom, because you don't have to ALWAYS correct him, but when you do, he'll listen. So don't discipline "fun" but do discipline defiance.
