I found the scene with the doctors quite odd including the outbursts where they basically try and strong arm her into keeping the embryo (if she's seven weeks pregnant, the use of 'baby' is a loaded term for my tastes*). Even leaving that aside - what's the preoccupation with the characters having children that seems to have overtaken the TNG books?
Hopefully they abort it between books and the female character isn't 'punished' for that choice as they are in so much literature.
* remember I'm English and the abortion question here isn't discussed in the same way as it in the US.
To me, the telling scene about the pregnancy was when Nancy and Harry discuss it - he says it's her decision and he won't try to tell her what to do. That's where we last check in on this story in the book, the final note that storyline hits for the time being. So regardless of the build up, the place we left this on is saying 'it is the decision of the woman that matters.' That said that there's going to be a respect of her choices and decisions, because that's the note chosen to end on.
As for the doctors reactions, they seemed rather even-handed to me, telling her 'this will save your life' and, recognizing that learning that she's dying and pregnant at the same time, this is something that she should consider some before making a decision, give her the facts and tell her to wait a while and think it over. It didn't feel like strong-arming to me, just laying out the facts and not accepting a snap decision that doesn't need to be made this very second.
As for the 'having children' thing, I think it's the fact that either the characters or the overall narrative has made a big deal about family. In TNG, we have Picard's family line being very important for him, which is why taking that step with Beverly was an important character advancement for him, that he could bring himself to have a child after years of emphasizing that he was uncomfortable with them. Sisko was always a family man - he was introduced with a son, the show ended with Kasidy pregnant. Voyager was always saying that the crew considered themselves a family, and Tom and B'Elanna got married and conceived Miral on the show, and it's a big part of their story that B'Elanna have this family, and has children who never experience what she did, seeing her father driven away by the 'Klingon stuff.' And while Riker and Troi might not have made it a big deal, Lwaxana clearly did, seeing her daughter married (presumably with the assumption of having children) was a major note for her characterization. Janeway having children was something that I seem to recall Kate Mulgrew wanting to approach and deal with, it was a factor in her portrayal, and we have Q saying that Denzit Janeway was the only one who had a child (whether or not you believe that Q has actually witnessed the infinite number of Janeways and seen this is up to interpretation). And that's still a handful of characters out of all of the 24th century crews, across the line.
I mean, I'm not even much of a children person, I don't want any of my own, and am about as uncomfortable as season 1 Picard around them. But I don't think there's an overemphasis on them. These novels have been about taking these characters to the next stages of their lives, and for a number of them, that includes children. If you take them all at once, yeah, it might seem overwhelming, but it's really only about one 'family unit' per series.
