My son forgets everything- just simple things like to comb his hair. His routine is the same every morning. I have notes all over the house, that remind him to do things. On the mirror, I have Don't forget to comb your hair, on the light switch I have Don't forget to turn off the light, just reminders all over the house. Is there a way to attach a note to his backpack, to remind him of something he needs to do when he gets to school?
