When I was in the 2d grade in my first week of public school, I took several Jack London books to class to read. The teacher took them away from me. That began a long battle whose end result was that the Library was my first hour of school and I was able to read by myself in class as long as I took the tests and was quiet.
As for "appropriate" - when I was 8 I got to shoot the hogs for the smokehouse. I was also driving tractors on the highway and carried a rifle with me when I was out in the field. I worked beside my dad and my uncles from sunup to sunset and they talked freely about just about everything. Over half of them were Army vets. It could get salty.
