How many outfits can one kid wear in a day?

B changes clothes multiple times a day. In an effort to curtail this current trend I lock his closet, but I let him choose his shirt for the day. Today we started with a blue and orange (his favorite color) shirt with navy pants. Over the course of the morning he added the hat and the knee pads.Outfit # 2 for today is the basketball outfit. This is kept in his dresser and I haven't locked those drawers (yet). I tried to explain to him that it makes my job as Mom harder when he changes clothes all the time. His reply was, "I put them in the dirty clothes when I take them off." My response, "Exactly, you are making TONS of laundry!" He doesn't seem to care...
