i’ve mentioned it very briefly before, but i have such specific headcanons on caitvi and parenthood
first of all, i think they’d wait multiple years post canon, at least five, possibly more. both would (initially) not want kids. then, vi would want them, and caitlyn would be against it. then, caitlyn would come around.
vi needs to heal from her lifelong role as a protector before any kids gets involved—she needs to learn how to be herself again. plus, i think she’d have a HUGE fear of leaving her child orphaned (which, valid, somehow this girl ended up triple orphaned) (orphan cubed), so she would want to wait to have children until the piltover was more stable. (i think eventually that’d lead to a bit of frustration within herself, bc she’d keep delaying having children until she finally admitted to herself that there is no objectively “right” time. she cannot guarantee her child’s safety, and while that’s deeply upsetting, it’s a reality she will have to accept before having children.)
caitlyn would not want children at first. she’s not against it, its just never been something that interested her. it was sort of expected her entire life, but she’s never put thought into parenthood on an emotional level, just the general understanding that she needs an heir to continue the family name. right now, though, she has a country to run, she has wrongs to right, she was so many amends she needs to make. a child simply doesn’t fit. and, i think she would have a really bad paranoia that if they were to have a daughter, their relationship would be similar to her relationship with her own mother. i think she also would be worried about putting the pressure of the kiramman name on a child, knowing how much she herself struggled. in general, i think the thing she’d be against isn’t children, its motherhood. she’s scared of being a bad mom.
