Having had a child this year, my greatest fear was that it might be profoundly autistic. I can't begin to imagine what it must be like to be stuck with a physiologically-broken child, for life, that is incapable of empathy or love for its parent. I appreciate that's the sort of thing that happens at the extreme ends of the spectrum and not at all representative of many high-functioning autists, but I don't think it's…
(I'm a parent of a kid on the spectrum) While the fear is natural, there are tons of other childhood conditions that are, in fact, worse than autism. Would you decline vaccines for yourself or your child because you fear they might "get autism" (which has been debunked). Edit: clarity
And also nope, because we ran the gauntlet despite our slightly higher age and subsequent increase in probability of autism (amongst many, may other conditions).
As I say, I don't think it's wrong to fear the possibility, and as your post admirably points out, life is inherently full of risks.
