I'm a bit confused with this article.

You say that parents should listen to their child (which I agree with) but then shame them for trying to find resources to help translate parts of their child's communication that they don't understand.

I assume that any parent who is reaching out to you, would have ALREADY have spent a long time with their child, years usually, every day, trying to figure them out and communicate with them, and it's usually a difficult realisation that "I don't understand my child as well as I would like, I thought as their mom/dad I would automatically understand them but I don't, and I desperately want to, let me try and find resources so I can try and get better at understanding my child".

For example, nonverbal autistic children, you say it should be "obvious" what all their nonverbal communication means, but the fact you say that while many parents don't find it obvious, is probably the reason they are reaching out to you. Because you DO understand something about the autistic mind that they don't. While of course acknowledging that all autistic people are different.

I feel like you're assuming that parents just don't care about their kids, and haven't tried what you're describing, that they simply throw up their hands at the first opportunity and say "OK let's get a psychologist to figure this out" when the vast majority of times (unless the parent is abusive in which case I doubt they'd be reaching out to you) they have been trying for a long time already on their own to make it work before seeking help.
