My 4 year old's room is constantly a mess. Usually once a week, we tell him to stay in his room and clean up. He usually does a decent job of it with some help from us. But he generally lacks the interest to keep it maintained.
Are there any ideas to help encourage him to keep his room is neater? I realize he is only 4 and I am not expecting a spotless room by any means. Just a room we can at least walk into without tripping over 50 items on the floor.
