@hironopiro You have a good question. So to answer your question I will give you my personal experience as a person with a physical disability and as a professional. First educating the public can be done in two ways one is by seeing. While you are out with your child people see how the child behaves in public as well as how you behave. Without any verbal or physical interaction. The public makes a conclusion just on what they see. For me it is a positive observation when they see me in public walking around being independent seeing this they may conclude that a person with a physical disability can be independent. Another way to educate the public is to get to your schools or parent organizations and lecture about your childs condition. Every bit helps. You will never be able to change or educate everyone and someone some where will act inappropriately to your child. Just know that so you do not feel you failed. It is just that. Your friends ADHD child can be a challenge. I would have your friend talk to her doctor about medication for her childs ADHD behavior. I know that is a hard reality but some times medication is necessary for the safety and well being of the child. Your friend I am sure is doing her best with her child but I would also look into support groups in her area for her own mental health. These other parents can share stories and things that did for child that might be helpful to your friend. I hope I have answered your questions. But what it comes down to in children and the public is that you can not control the public or allways their environment the best thing to do is keep up with your and your friends support group contacts and be willing to evolve.
