Not really sure what category to put this in as I don't think ADHD qualifies as special needs necessarily, but similar techniques for other disorders or conditions may be helpful here.
DD 11 is not diagnosed as I don't believe in medication for this condition in her case, but I'm pretty sure her memory issues are a symptom. What I need help with is that, specifically: she is very high functioning, so constant reminders only come off as nagging, but she only remembers to flush the toilet half the time (among other things) so I need some other techniques to get her to remember without coming off as condescending or "on her case" constantly.
She has check lists for things that are "check list-able", like getting ready in the morning and routines for after school, but I'm not really sure how to address the daily reminders to flush the toilet, put on her seat belt, etc. She is too old for clever songs or rhymes, so I need something that works on teens or adults. She also leaves things at school constantly and it is usually too late by the time she remembers, so I have her count what she goes in with but I can't remind her at the end of the day as she's coming out. Her school is split up in several small buildings and pick up happens at the main building, so by the time we leave the building will be locked by the time she goes back.
Has anyone tried any memory games or something that maybe inspire her to be more observant of things? I've tried everything I know, all the usual suspects, and nothing really works with her. She was evaluated by the professionals at her school since she was a late reader and they found no learning disabilities, so I'm thinking all the memory issues seem to be ADHD related. She also has no problem remembering things like her friends' parties or something she was told she would get, so it's definitely an inattention thing and not a general memory issue.
