Sofia Robbin Sloan Torres

Sofia Robbins Sloan Torres is the child of Callie Torres, Mark Sloan, and Arizona Robbins.

Callie's Pregnancy
When Arizona won a prestigious grant to help treat children in Malawi, a disgruntled Callie agreed to move there with her, as it was a three-year position. However, her lack of enthusiasm caused Arizona to end their relationship in the airport and leave without her.

A heartbroken Callie moved in with Mark and they had a short fling. Arizona returned for Callie, apologizing and hoping for forgiveness.

Callie initially rebuffed her and later revealed that she was pregnant with Mark's baby. Arizona agreed to raise the child with her, but disliked that Mark would be a permanent part of their lives.

When Callie was twenty-three and a half weeks pregnant, she planned a getaway-weekend to thank Arizona for her support.

En route, Arizona proposed to her, but before Callie could respond, they crashed into a truck. Callie was treated at Seattle Grace, where her daughter was delivered early. When Callie woke up, she accepted Arizona's proposal.

Sofia lost her father due to injuries in a plane crash.

Infant Struggles
Sofia was delivered by C-section during Callie's second surgery following the crash. Addison Forbes Montgomery, Callie's very good friend, returned from Los Angeles to deliver the baby, since she still held privileges at Seattle Grace Mercy West Hospital.

Sofia was delivered 16 weeks early without a heartbeat at 1 pound and 1 ounce. Arizona was able to resuscitate her and she was placed in an incubator as her lungs and other internal organs hadn't fully matured.

Dr. Lucy Fields failed to give Callie steroids before the delivery, which would have matured Sofia's lungs more. She was then brought to the NICU and was on a ventilator, as she was unable to breathe on her own.

In the meantime, Callie was struggling to recover from her surgeries and wasn't allowed to see Sofia. Cristina, who provided much emotional comfort to Callie, gave it to her straight: “She’s mostly tubes and wires and she looks more like a chicken than a baby, like a featherless, beakless chicken. You want to wait ’til she’s cuter”, to which Callie replied, "You're the worst godmother ever."

However, Cristina organized for Callie's stretcher to be driven to the baby care unit so Callie could get a peak at her daughter which she was very appreciative of.

Callie pushed herself too hard and eventually had to undergo surgery again to repair internal injuries sustained while pushing a stretcher carrying Cristina and Meredith.

At 5 weeks old, Sofia was in heart failure and required surgery which Dr. Stark performed.

He allowed Arizona to be in the OR as she is not biologically related to Sofia and it was not a legal issue for the hospital. During the surgery, Sofia started to bleed out which caused a devastated Arizona to run out of the OR.

However, Dr. Stark was able to find the bleeder and repair it and Sofia was stable.

After 12 weeks of recovery, Callie was discharged from the hospital, but reluctant to leave unless Sofia could leave with her.

Dr. Robert Stark, the pediatric surgeon on Sofia's case, eased Callie's tensions by allowing Sofia to be discharged if she passed the infant carrier test. She passed, but Callie was scared to take her home because of the dangers of cars.

Miranda Bailey calmed her down and Callie, Mark, Arizona, and Sofia left the hospital.
