@saramg @Tylae That's terrible. I'm sorry that that happened.
My son actually exhibited symptoms usually found in girls (inattentive style). So his teachers just thought he was being lazy. It wasn't until he was talking to a therapist that we learned he had ADHD, and my wife found out she had it at the same time because the therapist didn't realize she didn't know she had it.
Then we spent a year and a half fighting doctors and schools about the matter.
