Question: does callie lose the baby on grey's anatomy

Answer: No, When Robbins wins a prestigious grant to help treat children in Malawi, a disgruntled Torres agrees to move there with her, as the position will last for three years; however, her lack of enthusiasm causes Robbins to end their relationship and go without her. A heartbroken Torres moves in with Sloan, and they have a one-night stand. Robbins returns for Torres, apologizing and hoping for forgiveness, but Torres initially rebuffs her, and later reveals that she is pregnant with Sloan's baby. Robbins agrees to raise the child with her, but dislikes that Sloan will be a permanent part of their lives. En route a weekend getaway, Robbins proposes to Torres, but before Torres can reply, the two are in a head-on collision with a truck, leaving Torres severely injured. In an attempt to save her life, obstetrician-gynecologist Addison Montgomery (Kate Walsh), delivers Torres's premature baby. Torres survives, and agrees to marry Robbins. After twelve weeks of recovery, both Torres and baby Sofia are discharged and allowed to leave the hospital. Torres recovers from her surgery, but deals with the backlash from her mother (Gina Gallego)'s attitude toward the wedding and her granddaughter. Torres and Robbins marry in a garden after the minister's wife falls ill, with general surgeon Miranda Bailey (Chandra Wilson), officiating the ceremony.
