The title pretty much explains it all.
Theoretical background: There is a psychologic concept called automatic thinking. Those thoughts can be either functional or not. We assume here just that this automatic thought I am asking about is not unadjusted with the normal human response, given the constraints.
What might a female that is entirely uninformed about the existence of procreation, pregnancy and birth think, after giving birth all by herself? Will she, if she doesn't guess what it was that was coming out of her, actually care for the baby properly without the social knowledge that she should care for it in a given way?
P.S.:For the purposes of this question "a uninformed female" is NOT a character.
P.S.S.: No manner of fecundation happened, so she can't relate the birth to any prior event, be it traumatic or not. Read that as: There was NO abduction, NO sexual intercourse, NO weird interaction with anything she wasn't used to before being pregnant.
