Our 11yo boy often forgets simple things, such as taking his coat home, bringing home a needed book or paper, or turning off the light in the bathroom when leaving it. He regrets doing these things but keeps doing them. I wonder how to help him. To avoid losing things and forgetting things, some rules I try to follow and have suggested to him are as follows:

(1) Avoid carrying loose things -- put them in pockets when possible.
(2) Whenever leaving a room, ask yourself what you came in with and what you should have on you.
(3) Have a single place were you always put your keys, wallet, etc.

I wonder how parents have tried to ameliorate absent-mindedness in their children.
