Our narrator is Scout, a girl who will grow from 6 to almost 9 during the story. What do you suppose we, as the readers, should be aware of as we listen to Scout tell her story? Is a child a reliable or unreliable narrator ?

Scout begins and ends as a reliable narrator. Even at the age of six we can see she tells the truth mixed in with her childish eccentricities. As she grows up, Scout is able to look past prejudices and see things in a similar light, in her own way, as her father Atticus. 

I think scout is a unreliable narrator because she is only a kid and does not understand the world yet

Anna I'm gonna have too disagrue withe you becase Scount is a very reliable person even as a kid, as she tells the truth and grows to see the world in a similar light as her father Atticus, but in her own way. She also tells what it would be like back in the time period of the great depression.
