Yeah, this always happens. I’m just trying to think, maybe because most of the characters in this stories are young. So the heart out weighs logic.
It could also be loneliness, to have company. Most Mc’s don’t have family. To have something that’s yours, people do have kids out of loneliness. It’s not a good reason but it does happen.
As much as a love omegaverse kids… it would be nice to see a story that doesn’t use a kid to bind people together.

Or maybe no kids. It would be nice to see how a mated pair work things out without the kid. And when they are actually ready, and prepared have kids. It’s not the most interesting idea, but it would be nice to see a different spin.
I like the cute kids, but an MC on the run or struggling to provide. Followed by the sudden discovery of the ML and trying to insert himself back into the Mc life is sort of predictable. The kid glueing them together.
Whenever Omegas in Omegaverse got pregnant by their Love interest they never consider abortion. Even if Love interest treated them like absolute garbage they kind of stick to a glimmer of hope. Justification for this is pretty simple: My only family.
