So my 5yr old has his 2 cousins (7 and 5) here staying the night with him. Well they get to playing and he gets lazy. He decide's that he doesn't want to go to the bathroom to pee....so instead whips it out in front of everyone (his siblings and cousins) and pee's INSIDE HIS TOY BOX! How the hell do I punish him? I already made him clean and scrub the toy box out.
