I replied earlier.. but I don't see my post.. I may have responded wrong, so I will try again.. hopefully I don't end up responding twice..
My son forgets everything.. just the simplest tasks, and things he is suppose to do every single day. I made little signs all over the house- in the bathroom I have a sign on the mirror that says, don't forget to comb your hair. I have a sign on the door that says don't forget to wash your hands, I have signs in the shower that say don't forget to wash your hair and rinse it out. I have a sign on the front door that says "don you have your backpack, lunchbox, and glasses" These signs do seem to help remind him of just daily things that he forgets.. is there a way you can put some kind of sign or tag on the outside of his backpack, that isn't obvious and embarrassing that reminds him to give the note to his teacher- or whatever else you want him to remember?
