In real life, certainly. And what you're proposing is certainly a narrative direction that could make sense in some comics. Even some Spider-Man comics at that.
But I think you're neglecting to consider that Hickman has a bit of a formula here that has been previously seen in his Fantastic Four and X-Men runs, where the main protagonist is a 30/40 something year old father who is happily married, has children and has a father figure of his own. All of which we see here already in Ultimate Spider-Man with Peter, Mary Jane, the Parker kids and Uncle Ben fitting into the designated roles.
I absolutely believe that Hickman will throw family drama and
some form of loss at the Parker family's way as the story progresses. That's bound to happen and I look forward to seeing those developments. But I don't think the Parker kids will be dying anytime soon here.
If anything, I would argue that
if tragedy were to strike the main cast in such a way that it involves a child, my money would be on:
spoilers:
Gwen becoming pregnant at some point in the run and then later have a tragic miscarriage as a consequence of Peter and Harry's superhero-ing endeavors. Hickman made a point to highlight that Harry doesn't feel comfortable with bringing new life in the world he currently lives in- and that really stands out to me, considering that if you look back at Harry in the 616 continuity in say the J.M. DeMatteis Spectacular Spider-Man era, Harry loved being a father.
Moreover that sort of development would make sense enough in instigating a divide and tension between Peter and Harry. |

Now that isn't my main theory of what all could happen, but if we're feeling so confident that a child is going to die at some point, that'd be where
my money would land on. Your mileage will obviously vary though!
