Children in the MCU
 

Any thoughts as to what they're going to do with all the kids there suddenly are in the MCU? Instead of recasting characters will the idea be to just eventually replace them with their children?

* Tony Stark has a daughter.
* Thor has an adopted daughter.
* Scott Lang has a daughter.
* T'Challa looks to be posthumously having a baby son or daughter.
* Bruce Banner is probably going to return to Sakaar and find he has a son.

And then peripherally there's Captain Two-Moms and Ms. Marvel running around, too. Will they be placed in some kind of group?

Unless they bring back Tony Stark they wont do anything with Morgan. She's an original character anyway so it's not like they have any comic material to draw from. It's up in the air whether Thor will get another movie anyway. I'm keeping my bet that the teased followup fight with Hercules wont happen in an actual Thor movie. Wherever Thor shows up next I doubt she'll play a big role as again she's an original character with no story to draw from. If it's true T'Challa has had a son off screen it'll be the same deal. These only children were only created to give a happy ending to characters whose actors were retiring (or semi retiring) from their roles.

Now the ones who are from the comics will definitely be featured more prominently:

Skaar will have the same complicated relationship with his father that the comic version had and being sometimes villainous and sometimes heroic. I could easily see him inheriting Miek's place in the World War Hulk story as that would fit him quite well.

Cassie Lang will almost certainly become Stature like in the comics...or Stinger like her alternate universe counterpart. Elijah Bradley will become Patriot, Wanda's twins will magically grow up to be Wiccan and Speed and they will all team up with with Hailee's Steinfeld's Hawkeye a younger variant of Kang as Iron Lad and Hulking to become the Young Avengers. Whether that's a movie or a Disney+ series we'll have to wait and see.

Ms Marvel and Iron Heart are interesting ones because they aren't Young Avengers. The team they are a part of is The Champions but since we're ways off from introducing Miles Morales or Sam Alexander into the MCU they may just say they Young Avengers or stay as purely part of their own franchises.

So with the season finale of She-Hulk
