Now, I understand in some stories when an adult enters a child's body, it's weird for them to either act too mature (to the point it's very weird that a child is too adult-like and not that "I was forced to grow up too soon" mentality) or too childish (to the point that makes them look unnecessarily weak), but in this story... I feel like it would be okay for her to regrow as a child despite having an adult soul and mentality. She grew up poorly in both lives and now that she managed to escape from her current family... Arwyn should be allowed to experience her second chance at youth and not have to worry about money. Of course, she wouldn't want anything expensive but she also doesn't technically have to be frugal since Shelly's family loves her so much that they are willing to give her anything.
