Avoid ADHD Guilt, Accept Each Other's Imperfections
You may have challenges like those of your son, but he is his own person. ADD/ADHD is an explanation of behaviors, not an excuse for them. Your own failures don’t mean you shouldn’t have reasonable expectations for him.
It is difficult enough to deal with your own ADD/ADHD, let alone your teen’s. Don’t let the perception that you’ve failed as a parent, because of your daughter’s challenges, affect your interactions with her. You are a role model for your daughter, imperfections and all.
