They will stay as children for this game.

The only reason they got a "jumpstart" was for you to be able to interact with them.

And of course, for them to have a distinct appearance aside from being an useless roll of sheets with a face poking out.

Having the children grow up would be a nightmare, due to the ability to have multiple kids with each LI. Keeping track of each one's progress would pose significant writing and coding issues, not to mention the headache it would cause you as a player trying to keep everything straight. That, and once the kids grow up, people would be complaining that they can't be intimate with them, dragging the incest issue out even more.
