Thank you for this. My sons are HFA/Aspergers, OCD and GAD, and may get agitated and embarrassed if they hear me talking about their diagnoses and needs. Like the OP's daughter, there is often nothing in their appearance or mannerism to indicate autism/OCD/anxiety until we have hit that "point of no return". I was wondering how to discreetly notify the TSA workers, so these cards are great.
