yeah, no. i'm not done having feelings about Keiko and her motherhood.
i don't believe motherhood is something Keiko resents. i believe it is, in many aspects, fulfilling for her. but it is also a labor that monopolizes her time such that pursuing other fulfilling things becomes increasingly complicated.
and of course, her motherhood is indubitably tied to her marriage, which i think is the biggest source of those complications.
Miles' career both ensures he has very little time to spare for his family and that Keiko is uniquely isolated from the realm of work she's crafted her own career for. Molly, by necessity, must go wherever she goes, all while Miles is off getting himself into cosmic blunders and devastating torment nexuses (nexi?). to be fair, none of Miles' work is really any place for a child, but it doesn't change the fact that it leaves Keiko with the brunt of what should be a labor of partnership.
whether or not they ever discussed this as a feature of their marriage is kind of... null? their parenthood, as it pertains to their partnership, never really gets brought up. we see Keiko upset about the move - as she has every right to be. it's an action that uproots their entire family and puts them in considerably more unpredictable danger than living on the Enterprise did. and we see her concerned for Molly's safety aboard the station, but we see no conversation about how she and Miles will share parental responsibilities. as if there is an unspoken understanding between them we aren't privy to. and we have to assume they came to a mutual understanding about it because the distribution of parental responsibilities never seems to be a real point of contention in their relationship.
we do see Keiko express frustration over the way DS9 limits her access to opportunities for botanical research and, to Miles' credit, he does try to help her find avenues to continue her career. yet, finding botanical research to contribute to down on Bajor means further separation between them. which also leave Keiko the one solely responsible for Molly's well-being while she is pursuing. something that, interestingly, she doesn't seem to have many concrete thoughts about other than exhaustion upon returning to the station. which, fair. i'd be exhausted, too. but the source of that exhaustion isn't explored in any particular detail.
i guess what i'm saying is it feels like the show takes Keiko's motherhood for granted. of course, she'll take care of Molly while Miles works. of course, she'll abandon everything she's ever known and everything she's been working towards for her husband's reassignment to DS9. of course, she'll be there to pick up the broken pieces of her husband every time he comes home from some inexplicable horror.
what is it she's doing on Bajor? oh, just plant stuff? well, then it shouldn't be hard for her to take care of a whole ass child on her own while out in the field.
moreover, i think these assumptions bleed into the whole teaching subplot in season 1. the question of her qualifications are left rather nebulous (seriously, who decided a career botanist had the credentials to teach???) and her desire to even start a school comes from observing behavior in the station's children that she finds disconcerting. it is definitely something to devote her sudden excess of free time to, but her motivations seem to come more from a place of wanting to keep children out of trouble than an actual desire to teach. which, quite frankly, is the wrong reason to get into teaching.
despite all that, she seems to do well in the position and leaves a lasting positive impact on the station's children, namely Jake and Nog. but again, i'm tempted to question why her ease with teaching seems to be taken as a natural extension of her motherhood rather than something she's truly passionate about. her general apathy when the school eventually closes down seals the deal for me: teaching was not as fulfilling for her as botany is and was never going to be.
i think the show's propensity for painting Keiko's motherhood in this light comes from the patriarchal picture of motherhood as some inherent drive to give care and to nurture in all those with the capacity to give birth.
firstly, this picture assumes that motherhood is a universal experience, that caring for and nurturing young looks the same for everyone and everything (watch Isabella Rossellini's series of shorts, Mammas, for a very concise and helpful demonstration of why this is patently false).
secondly, it assumes that motherhood is written into the biology of those with the capacity for pregnancy. that it comes naturally, so why should it be resisted? why should it be hard?
and thirdly, it presumes that motherhood is always a rewarding function and experience, something that is natural and desirable and necessary and therefore inherently virtuous.
while we get entire B-plots devoted to Miles' struggles as a frequently absent father, we don't hear about any of Keiko's particular struggles with parenthood because the show treats her motherhood as a piece of background information.
her relationship with Molly as her mother and as the most present and available parent is given very little dimension because the show writes it as this static, unquestionable thing. it is only given dimension in opposition to the challenges Miles faces as a father. Keiko knows the particularities of Molly's routine, playtime and food preferences because she spends the most time with her, but the show never considers the possibility that that comes just as much out of necessity as it does out of genuine love for her daughter.
never considers the possibility that Keiko might have objections to shouldering all parental responsibilities while also conducting botanical research.
never considers the possibility that she might have struggled to teach beyond some creationist analogy spat between her and Kai Winn.
never considers that she might fantasize about leaving the station to continue her studies somewhere else for a while.
never considers how having her baby transferred to another's womb in the midst of a medical emergency might make her feel, how it might impact all the preparation her body and mind had been doing to deliver a baby that is not longer there.
never considers that being possessed by a pah-wraith might impact her relationship to motherhood, having been unable to do anything but watch as this being ruthlessly held her and her entire family hostage for their own interest. i mean, does she ever have nightmares about hurting Molly and not being able to stop herself? does she have nightmares where Miles wasn't able to save her?
never considers that motherhood for Keiko might be imperfect. does it ever feel oppressive? does she hate it sometimes? does she wish things were different?
we'll never know. we'll just never fucking know.
