Hey, I can't seem to see your comments on my octonauts fanfic, but I can see them in my notifications :/
Anyway, I'm in the process of writing the origins, which, as the name suggests, is a multi book series for how the octonauts came to be. It's currently on hold until my writers block for it lifts, but the point is it's coming. That being said, I don't think I'll be doing all of them with kids unless you just want some one shots or head cannons.
