Didn’t want to say it, but it sure seems trendy to me. Quick example from my daughter:

She had zero issues with eye contact until very recently. She reads memes telling her eye contact is a problem for people like her. Now she has problem.

I am NOT saying that issue is fake, but when a child is constantly bombarded with, “This is how you are!”, they become that way.

Part of my thoughts in the OP are, “We’re making normal behavior out to be abnormal and slapping a label on it. And perhaps we’re making it worse than need be.”

My mother constantly told me I was sickly as a child, and I was constantly sick. First year of college (without her influence) was my first year without a single illness, not even a mild cold. Miracle! Wait…
