I still think should Stephanie continue caring for her child, chances are she’s going to get a job to support herself and her family which would mean she’s going to make Tim help her look after them. If some people do become attached to their children, as with some mothers (based on a documentary I watched) then losing the child by having them adopted by somebody else would be just as bad. I also think some essayist had a good point about the portrayal of motherhood (and child-rearing).
Not only does it interfere with idealised sex fantasies (not just with the pregnancy part but also where said female character may end up nagging at her male counterpart for not helping*) but also where it’s sometimes treated with suspicion or at least any degree of it. Madelyne Pryor, who begat Cable, turned out to be working for Mister Sinister and became evil. Stephanie Brown got impregnated by another man and was something of a troublemaker.
Cassandra Cain and Damian Wayne have villainnesses for mothers and both Cable and Rachel ended up being raised by somebody else. (The latter being Jean and Scott’s children though Jean did raise the former and Scott cared for the latter.) I don’t think it simply affects children but also nieces, nephews and even grandchildren.
Supergirl is Superman’s cousin but for an extended period of time her own relation to him got changed significantly and even in the older stories despite meeting Superman she ended up being raised by people other than him (in Superman’s defence he was practically orphaned upon arrival). Bart Allen came from the far-flung future and his own relatives were sent to live there or something.
Not only that he also got raised by somebody else, killed off, then reappeared with his relation to Barry changed and then reverted back. Sometimes superheroes’ children are never to be seen away, whether if they’re ignored or killed off (in Punisher’s case). I mean we could’ve gotten stories where Tigra not only hunts pests for a living but also takes her child to hunting and fishing trips.
Some mothers do the same to their own children and some women in general do hunt. Same with Stephanie Brown getting a job to support herself and her family, it’s not even unprecedented in superhero comics since Peter Parker did similarly and Supergirl also worked as a waitress (earlier still as an actress).
It’s not that motherhood and parenting are entirely devalued in superhero comics but that it’s hard coming up with superheroines who’re also dedicated biological mothers and aunts. Chances are such examples are few to begin with where you only have Jean Grey, Susan Richards and Helen Parr. There are good stepmothers like Rita Farr.
But having a superheroine remain a dedicated biological mother/aunt’s even rarer, hence why it proves somebody’s point right in linking superhero mothering with anything a little fishy (illegitimate impregnations, sometimes stemming from rape and the like). And why we never get to see Steph as a dedicated working mother.
Or Black Canary being Tim’s loyal but somtimes overprotective biological aunt.
