I’ve given it a little thought, I’d imagine it might be akin to the Fluffy version of an empath, a Fluffy that can attune themselves to the emotions of other Fluffies. Or perhaps one that can talk and eat soft foods but is fully dependent on their parents even into adulthood.
That second one has great sadbox potential for a feral herd, I might use that.
I have also thought of the opposite, a mummah claims their babbeh is sensitive but the foal has no idea what mum is talking about.
I don’t really go with the sensitive baby=autistic concept myself.
I see them more as overly coddled to the point of being unable to care for themselves, like a bestest baby taken to the worst extreme.
To be honest the term originated from a story where the condition of the foal in question wasn’t really explained, hance why everyone just linked it with any kind of mental disability. I think now is a good time to ponder what sensitive baby is exactly
Thats where i first saw it.
As far as I am concerned i agree with @Karn sensitive is not autistic
The purple foal clearly has extreme issues, and can’t and won’t take care of it self.
