Yes, but if you never take the car and pretend it is driving, that’s a bad sign.
And all babies should make eye contact. That’s important.
While it is subjective, these signs would also be pervasive.
I am not even beginning to imply that autism is a “fashionable” disease (as some have called it) or to imply that a lot of these diagnoses are bullshit.
I just want to point ot that it is hard to come up with “hard” figures for something that is not easily and objectively defined: no antibodies, no pathology, only behavioral indicators, which can be misread.
