In To Kill a Mockingbird, how does Harper Lee portray Atticus as an ideal father?

One of the ways that Harper Lee uses to portray Atticus
Finch as an ideal father is through his concerned involvement with his children. He
unhesitatingly answers their questions; he gives them advice about life; he does not
attempt to protect them too much from the world because he knows that they will need to
deal with it. By using Scout's perspective on Atticus in the story, the reader can see
how much she loves and respects him, which is a clear indicator that he is a good, maybe
even an ideal, father. He also gives his kids enough space to figure out things for
themselves and lets them make mistakes. These are all qualities of a really good dad.
