Firehouse 51 has an adorable new face on set!

How to Watch

Watch Chicago Fire Wednesdays at 9/8c on NBC and next day on Peacock.

On February 7, the Chicago Fire gaffer and chief lighting technician Anthony Lullo posted the most adorable photos of Kara Killmer's (Sylvie Brett) onscreen daughter, Julia, behind the scenes of the show. In the pictures, the baby is being taken care of by an onset nurse while she sits on a play mat surrounded by toys. We also catch a glimpse of a doll being used in the baby's place, as Killmer and Daniel Kyri (Darren Ritter) hold it. 

''Baby Julia. We use a dummy/doll for rehearsal and the baby is only handled by our registered onset nurse unless filming. 👶'' Lullo revealed in the caption of the post.

We were introduced to baby Julia in Season 12, Episode 4 of Chicago Fire when she spent a few days a Firehouse 51. Julia is Brett's daughter, who she adopted from a teenage mother named Amber. So far, the Firehouse 51 squad has welcomed the baby with open arms. 

Why Brett is leaving Chicago Fire

Becoming a mother hasn't been the only exciting step in Brett's life lately, as she announced in the Season 12 premiere that she plans to leave Chicago in order to move to Portland to be with her fiance, Matthew Casey (Jesse Spencer)

"Matt and I talked it through and the truth is we've waited long enough to be together full-time," Brett said in the episode.

In an interview with TVLine, showrunner Andrea Newman explained the creative choices behind why characters such as Brett are departing the show

“Honestly, longevity is really just part of it. [In] storytelling and in terms of real life, 12 years is a long time and things need to change, just dynamic-wise. You want new characters and you want new dynamics.  Actor-wise, 12 years is a long [time]. Nobody expects in TV [that] they’re going to be anywhere for 12 years, I can say that for sure, from all sides,” she told the outlet. 

"To really get to arc these things out and see these characters change. But you need to mix it up. It can’t be the same the whole time. There’s still Boden at the helm and Severide and Kidd. It still feels very strong, and it still feels, because we’ll see Matt Casey, like most people who’ve been part of it are still part of it in lots of ways. So that’s lucky for us, too," she added.
