For what it’s worth, at least some of your son’s challenges are probably exacerbated by the normal forgetfulness of the teenage years. I have one son with ADHD and one without. I was sure that all of the forgetfulness and losing things I saw with my ADHD son was due to his ADHD – until his non-ADHD, supremely organized brother hit age 13 and overnight became just as forgetful. So go easy on both of you. It does get better.
