Neurodivergent and potentially ND kid questions are abundant on the site, and there are some very good questions and answers pertaining to the issue. Neurodivergent kids are not off-topic, and unless someone is asking about medicating them, they are usually fine. The title of the question, though different from the body, is worth addressing.
This community may be too careful about medical advice
For the record, if anyone on this site is overly cautious about medical advice, it's me. I trained in Family Medicine and practiced Emergency Medicine, and have a lot of experience with kids with all kinds of problems, including neurodivergent kids. I would be far more comfortable with medical advice if 90% of the time, it wasn't wrong.
Everyone has some experience with health care, and every culture has certain beliefs as well which are often repeated. This tends to engender a feeling of confidence in the medical advice one gives. However, one person's experience, or knowledge of a friend's or an acquaintance's experience does not a medical expert make. As a real-life "medical expert", it's easy to evaluate a user's advice, and I have absolutely no issue with it if it's correct. However, much more often than not, it's incorrect but still gets upvoted because someone else believes the same thing, and occasionally it's downright dangerous. So, rather than having someone on the site responsible to evaluate all the medical advice given for accuracy and challenging the erroneous advice in comments (which almost always digresses into a discussion and someone taking offense), it just isn't allowed. That is really the best course for this site.
