One common theme is family expansion. For example, a couple from the show might have a baby, and the fic would explore how they balance their work at the firehouse with their new family life. Another theme could be the support system within the firehouse. When a character has a baby, the other firefighters might step up to help, showing the strong bond among them.
Protection. Given that it's a show about firefighters, protecting the baby from harm, whether it's from a fire or other dangers in the city, is a big part of the fanfiction. The characters will go to great lengths to keep the baby safe.
I'm not sure of specific 'Chicago Fire' baby fanfic titles off the top of my head. But you could also look on Tumblr. There are often fanfic recs on Tumblr pages dedicated to 'Chicago Fire'. Some fanfic might focus on the idea of a character becoming a new parent, which could bring a whole new dynamic to the character relationships within the show.
Most likely not. The idea of spanking in a fanfic related to 'Chicago Fire' seems to be inappropriate as it goes against the general themes of the show which are about heroism, rescue, and the camaraderie among the firefighters. It may also be considered offensive or at least not in line with the family - friendly nature that the show generally has.
I'm not entirely sure specifically as 'fanfic' can vary greatly. But generally in a 'Chicago Fire' fanfic, it might be about the characters from the 'Chicago Fire' show. However, the'spanking' part is rather odd and might be a very specific and perhaps unorthodox take on the characters' relationships or situations within the fan - created story.
There are often fanfictions where a character in Chicago Fire has a surprise baby. In these stories, the drama unfolds as they struggle to balance their dangerous job with new - found fatherhood or motherhood. They might have to deal with the fear of leaving the baby without a parent if something were to happen to them on a call. It adds a whole new layer of emotion to the story.
A crossover could involve a character from Chicago Fire having a personal connection to a case the Chicago PD is working on. Maybe a firefighter's family member is wrongly accused of a crime. The firefighter then teams up with the PD detectives to clear their family member's name. This would bring in elements of loyalty, family, and the different skills of both groups. They could share information and resources to solve the mystery.
Another theme is professional growth. Fanfics might show how they learn from each other and improve their skills as firefighters. For example, Casey might teach Dawson a new technique for handling a certain type of fire, and Dawson could share her insights on dealing with victims.
One idea could be a story about a new recruit who has a hidden past as a firefighter in a different city and has to prove themselves to the Chicago Fire team. They might face challenges like adjusting to the different procedures in Chicago while also dealing with personal issues from their past.
