Yes, Callie and her baby survive.
While Callie faces several challenges throughout the show, including a devastating car accident, she and her daughter Sofia ultimately both survive.
However, it's important to note:
* Callie's daughter Sofia is born from her relationship with Arizona Robbins, not from a relationship with another character.
* The show's writers often put characters through intense trials and tribulations, making the audience worry about their well-being. So while Callie and Sofia ultimately survive, there are moments where their survival is very much in question.
