How can the relationship between Atticus and his children be shown with quotes in the first three chapters?

Atticus is usually frank with his children. He speaks to them as he would to adults. He shows them respect and is usually patient with them. He also enjoys spending time with Scout and Jem. One day, Atticus shows his honesty with his children when Scout asks if they are poor:

"Are we poor, Atticus?"

Atticus nodded. "We are indeed."

Jem's nose wrinkled. "Are we as poor as the Cunninghams?"

Atticus is usually frank with his children. He speaks to them as he would to adults. He shows them respect and is usually patient with them. He also enjoys spending time with Scout and Jem. One day, Atticus shows his honesty with his children when Scout asks if they are poor:

"Are we poor, Atticus?"

Atticus nodded. "We are indeed."

Jem's nose wrinkled. "Are we as poor as the Cunninghams?"

"Not exactly. The Cunninghams are country folks, farmers, and the crash hit them hardest."

Atticus said professional people were poor because the farmers were poor. As Maycomb County was farm country, nickels and dimes were hard to come by for doctors and dentists and lawyers (Chapter 2).

Atticus does not hide the fact that they are poor from his children. He tells them they are poor, and also explains why. In this way, Atticus is frank with his children and also respects their intelligence.

Sometimes, Atticus does treat his children with typical parental firmness. One day, Atticus scolds his children for playing loudly outside. Mr. Radley is near death, and Atticus does not want his children to disturb the family with their noise:

But there came a day when Atticus told us he'd wear us out if we made any noise in the yard and commissioned Calpurnia to serve in his absence if she heard a sound out of us (Chapter 1).

Atticus enjoys spending time with Scout and Jem. He often reads with them at night. On the night of Scout's first day of school, Atticus reads to them and keeps them laughing:

Atticus kept us in fits that evening, gravely reading columns of print about a man who sat on a flagpole for no discernible reason, which was reason enough for Jem to spend the following Saturday aloft in the treehouse (Chapter 3).
