The thread is not specifically about sleep issues. For instance, I am sure a lot of parents with AS children have been told their children are just spoiled. I know at least one person who have had both the people they know and a professional tell them this. It is not about getting the advice, it is about not being believed when we say we have seriously tried this course of action.
My daughter for instance refuses to eat most vegetables. A lot of people in my family were like this early in life. It could very well be a case we have the TAS2R38 gene, which causes a high sensitivity to the bitter taste found in vegetables. Sometimes there are real reasons behind these issues.
