Some days ago a boy came to me and told me that the father of another boy had told him that his son had missed class because he had to go to the psychiatrist. He told me like it was a big deal and he didn´t know the reason for that visit to the psychiatrist, but I could tell that for him going to the psychiatrist equals being crazy. So my reaction was to explain to him that that kid has ADHD and that´s why he goes to the psychiatrist. He didn´t know what it was and I didn´t have time to explain further at that moment. Now, I know I probably shouldn´t have said anything about it, but I didn´t want him to believe that going to the psychiatrist is wrong and for some reason (given how common it is) I thought that he would know what ADHD is. So my question is, is it useful/recommended to explain children about it? I would say yes, but I´m not sure what is the best way to explain it to them. Any ideas?
