Teresa Castillo, who portrayed Sabrina, was pregnant in real life with a little boy during this time so her pregnancy was written into the show. She went on maternity leave on January 28, 2016 and returned on May 20, 2016.
Teresa confirmed on Instagram that her son, Sebastian James Aaron portrayed Sabrina's son in a picture on March 9, 2016.
Twins Eli and Ilee Alzubaidy debuted on April 25, 2016 and made their last appearance on September 21, 2016.
Teddy was conceived during a one night stand in May 2015 while his father was hiding from the police in his mother's apartment.
Sabrina found out she was pregnant very late in the pregnancy and took multiple tests to confirm as she didn't want to believe it. Also at one point there is a question of paternity as she slept with Carlos at the beginning of May and Michael at the end of June but the baby turned out to be further along than originally thought therefore the baby was Carlos'.
In October 2016, she and her best friend, Felix DuBois are at The Floating Rib when Sabrina gets nauseous to the point of throwing up like she did when she was pregnant with her late son, Gabriel. Sabrina tells Felix that she is getting over the stomach flu. Felix recognizes the symptoms from last time and straight up asks if Sabrina is pregnant and Sabrina denies it, at first but agrees to take a test. After buying the test, Sabrina goes home to take it only to realize that she has wrong bag (Sabrina and Valerie take each others bag after bumping into each other at Kelly's) and then she goes to get another test, that comes back positive. After finding out, Sabrina takes multiple other tests to confirm it.
She puts off telling Michael Quartermaine and everyone else for a couple of weeks. While Sabrina was trying to hide it, Tracy Quartermaine guesses that Sabrina is pregnant. Later that day, Sabrina tells Michael and he is elated to be a father. Soon after Michael proposes but Sabrina turns him down, knowing that they aren't ready. However, on Halloween, Sabrina confirms with her best friend. Felix DuBois that the baby could be Carlos' or Michael's. On November 23, a very much alive Carlos shows up on Sabrina's doorstep and she passes out. On December 3, Sabrina confirms with Felix that the baby is Carlos' and later on, she and Michael went into for an ultrasound (she was 26 weeks along). While at the hospital Carlos overhears Sabrina and Felix say that the baby is his.
On December 4, 2015, Sabrina confirms with Carlos that he is the father and Sabrina also feels Teddy kick for the first time. On December 22, Sabrina finally tells Michael that the baby is Carlos'. On January 3, 2016, a very pregnant Sabrina goes on the run with Carlos.
At one point, Tracy had custody of Teddy.
His father, Carlos died on May 13, 2016, after being stabbed by Julian Jerome. His mother, Sabrina died on September 14, 2016, after being strangled by Paul Hornsby, making Teddy an orphan.
He is now under the care of his paternal uncle Dr. Joe Rivera.
Teddy was born onscreen January 28, 2016 to mobster, Carlos Rivera and Nurse Sabrina Santiago and was delivered by his father. Sabrina went into labor while on the run with Carlos. She gave birth naturally to a silent baby. It was later revealed that Sabrina had a healthy baby boy.
On April 25, Teddy is seen with his sort of great-aunt Inocencia in Puerto Rico. On May 17, a baby showed up on the Quartermaine's doorstep and Tracy finds him. She decides to call him Edward and tells Monica that she has no idea whose baby it is. Later on, Michael comes by and he sees the baby in Tracy's arms. Tracy tells him that the baby was left on their doorstep with a rattle. When Michael sees the rattle, he realizes that the baby is Sabrina's.
After talking to Michael, Tracy calls Dr. Hamilton Finn to make sure that Teddy was healthy and it turns that he is as Dr. Finn gave him a clean bill of health. When Tracy turns her back, Michael takes Teddy to GH and then he is put in foster care for the night. Teddy ends up at the PCPD with a social worker and that it where it's confirmed that he is in fact Sabrina's son. He also spent time with Michael while at the PD. Later on, it is revealed that Tracy applied to be his foster mother and later that day Eduardo was brought to his new home.
Days later, he is reunited with his mother, who reveals that she named him Eduardo and nicknamed him Teddy, after Edward Quartermaine, which is ironic because Tracy started calling him Edward. After some arguing between Tracy and his mother, he is finally put in his mother's arms.
On June 8, Dillon took pictures of Teddy in Lila's garden. Later on, his mother shows up and announces that her legal troubles have been resolved and she wants to take her son. After hearing that, Tracy gives custody back to Sabrina and offers to let her and her son stay at the mansion and she accepts.
Teddy becomes an orphan after both of his parents were tragically murdered in 2016. He goes into the care of his paternal uncle, Joe Rivera and leaves Port Charles with him.
