Yes.I'm trying to remember whether or not the Chozo thing made Samus sterile but this is honestly only happening in a lab either way.
I know people are trying to say this is their willing spawn by natural causes but in a realistic world this thing would be something the Galactic Federation cooked up out of a mix of Samus and Ridley's cells in yet another stupid attempt at science.
At that age it should still be in it's feather stage, though. Unless it progresses through Ridley stages at Ridley speed but the human stages at human speed? It would explain the deep questions.
I imagine Samus adopting it but being incredibly conflicted the whole time.
It's... it's a thing that Samus is sterile. That was kinda the biggest thing behind the baby metroid imprinting on her meaning just that much. "The Baby" was the closest thing she'd have TO a child (or at least that's how the writing tried to handle it; ignoring how far adoption or surrogate work would be possible in the age with intergalactic space travel).
The real neat thing about this angle is that it gives a second meaning to a famous line in the series. "The last Metroid is in captivity. The Galaxy is at peace." Samus giving up that child for that peace.... which makes what came of that all the more cruel.
