How about she be a true Logan clone and not actually grow taller? She just grow old around her small frame.

Whatever you are, be a good one.

PMS/PMT is a real thing, but it shouldn't be called that, exactly. Both men and women go through fluctuations in hormones throughout each month/year. People just assume that because we women menstruate that we are the only sex that has mood swings and hormonal changes. It is what led us women to be labeled "addled minded" and other such things for the last several hundred years.

According to modern feminism PMS does not exist. Some women are just on a regular 4 week cycle of mood swings. But that is not the same thing.
And if you insist that it is the same thing and that PMS is real, they are going to tear you to shredsespecially if they are PMS-ingI mean if they are on a regular mood downswing.
Be warned.

she will hit a growth spurt in a year or two when she enters puberty
The question then is how many people die when she gets her first bout of PMT?

In the comics only her claws are adamantium.

Yes, I also always assumed Magneto reattached Logan's claws for him. The end credits scene shows Logan still with bone claws (if I remember right), and also shows Magneto and Xavier on the same side. So now all they need is a little adamantium, which could be procured by retrieving his severed claws.

I think Adamantium is specially adapted to grow and repair with bones.
Per "The Wolverine's" mid credit scene, Wolverine had bone claws for at least two years.
It's the only explanation I could think of for why Logan's claws were metal in DOFP despite being slashed off in The Wolverine.
You couldn't think of the possibility that they found some more adamantium and recoated his claws with it because they were going up against sentinels and he needed his adamantium claws back to be useful so it was kind of important?
It's not even that hard. The owner of an international corporation owned him one. The same corporation that spent months cultivating contacts to procure enough raw adamantium to build a whole robotic suit. If he got some raw adamantium and melted it down any metal smith should have been able to recoat his claws since the entire process can be done externally (and thus would be nowhere near as complicated as the full skeletal procedure Stryker deviced).
It's also possible that since Magneto was now a member of the team and he can reshape hardened adamantium they didn't even need raw adamantium and just needed to either get a chunk of Yarada's suit or Wolverine's discarded claws (assuming he didn't collect them after the battle and take them with him) from Mariko. Or, if Mariko for some reason couldn't help them out there should have been a nice chunk of adamantium buried in a certain Canadian base that Magneto should have been able to detect and pull to the surface.

Well as far as the comics goes, X-23's bones aren't coated with the adamantly on her bones.

I think Adamantium is specially adapted to grow and repair with bones. It's the only explanation I could think of for why Logan's claws were metal in DOFP despite being slashed off in The Wolverine.
