So, I’m having a bit of a difficult issue that I don’t really have the expertise or knowledge of handling correctly.

So, here it is. The story is about a 6 year old girl who is cursed with extremely slow aging, one day for her body is the equivalent of 240 years. However, it’s the opposite for her healing, think wolverine or Deadpool, except times that by a thousand.

Anyways, she’s technically in her twenty’s, but lives with her older/younger twin brother.

What I’m having difficulty is her mental state by this point. I’m wanting her to occasionally act like an adult and talk like one, but still have her childish stubbornness and the occasional tantrum as well.

So, any suggestions? I’m all ears.
