I'm open to the idea that I'm over sensitive on this particular topic. To explain the parent POV a bit further - there is a fine line between giving a parent an actual recommendation, and inadvertently implying they are just a bad parent and that's why their child has issues.
An occupational therapist sending home a list of exercises to do? - A recommendation, of course.
A disapproving stranger staring down their nose at a child with ARFID and sighing "Well why don't you just tell him he has to eat whatever you serve? That's what I did with my children and it worked great." - Inadvertently implying a child only has issues because they have crappy parents.
I guess it's a matter of the person coming from a place of actual expertise vs. making knee jerk judgements about things they don't know much about.
"Practice waiting in line" isn't always going to be a terrible recommendation, I think the issue is that it's on a page for ND adults and parents of ND children, at all different levels. For some of those children, it may be perfectly appropriate. For other people, it might be like saying "Practice not having anxiety and loving crowds, because Disney will be more fun if you don't have anxiety and love crowds." Like, um... no s*** Sherlock, lol. If I could snap my fingers and make that happen I wouldn't be reading a page on disabilities.
I think a page like that is probably just too general as a "Disabilities Info Page". A doctor or therapist wouldn't give a list of blanket recommendations or exercises for all ages and support levels, because clearly many would be nonsensical depending on who received it.
