Danny is a cute, young boy who has a tendency to procrastinate.
In the episode Forever… Amen, Danny was excited that he was going to get a little brother he named Billy. However, after talking to his friend Harvey at the hospital, he decided he didn't want a brother anymore. Unfortunately, the baby didn't live to be born, and Danny felt responsible for Billy's death. Danny later dreamed about meeting Billy, who was actually a girl, and afterward he didn't feel guilty about his wish anymore. In the episode All the Difference in the World, he is friends with Jeff Marsden. He also plays the piano and did so for a talent show at Whit's End in The Secret Keys of Discipline.
Danny was also bullied by a same-aged-girl named Melissa in Afraid, Not!, because she thought he was cute. He told her he wasn't interested in her, which made her follow him on his walk to school every morning for several days. Melissa finally got hot-tempered and punched Danny in the eye, sending him to the nurse's office at school. With some guidance from Whit, Danny later overcame his fear and learned Isaiah 41:3 in order to keep him safe as he walked to school.

Danny Schmidt: Privileges?
Harvey: You know. Special stuff. Like staying up late, or playing over at a friends house.
