In a WIP, I have a main character who's an eleven year old boy, and the story's target audience is also young boys and girls. Now, when I'm referring to a character, can I use the term that the MC would use, or be more explicit? It's not a narrative, but closely follows the character. The word in particular that I'm having trouble with is "dad." It seems strange in some places where it's not the MC speaking: "Turning to Johnny, Dad gave him a reassuring look." vs "Turning to Johnny, Johannes have him a reassuring look." If I were writing for an adult audience, I would take the second one. But I'm wondering if I'd get a more personal connection to a young reader if I refer to the adults as they would? Should I use both and have it depend on context?
