He will go by Wiley Cooper-Jones until he is given back to his father.
He was born onscreen July 30, 2018.
Jonah Corinthos was conceived during his parents' brief relationship in 2017.
On December 7, after Michael cuts ties with Nelle and suggests she start over, she announces she's pregnant with his child. She claims she took a test the day before and is about six weeks along. However, Michael wants proof.
Later on, Dr. Kim Nero confirms the pregnancy and that she is six weeks along. They run into Carly afterward and Nelle gleefully congratulates the expectant grandma. Both Michael and Carly demand a paternity test and Nelle doesn't look happy and makes it clear she doesn't want money. Nelle eventually agrees to a noninvasive paternity test.
On December 20, Michael and Nelle discuss the baby.
On December 22nd, (Christmas on the show), Nelle is seen talking to the baby after finding out Kelly's is closed.
Later on, Nelle showed up at the Corinthos house and fainted in Michael's arms. She comes to on the couch and explains that she was going to get food but nothing was open so she started driving home and came upon a down tree in the road and got out of the car. She states she didn't mean to end up at the Corinthos', but she started walking and felt faint. Sonny brings Nelle some broth to warm her and the baby up.
Michael asks if she's in any pain and Nelle asks if he's worried about the baby even though he doesn't know if he's the dad yet and Michael says yes. Nelle tells him that they're warming up and they're gonna be just fine. Nelle ends up spending the night at the house.
It was later revealed that Nelle has fainted a lot and it was due to low blood pressure. She was told by a doctor to take it easy.
On January 16, an amniocentesis confirmed that Michael is indeed the father.
On January 22, the baby has appeared in a sonogram, which Nelle would later show Michael after he missed the appointment.
On February 22, Michael and Nelle attend childbirth class.
On March 6, Nelle suffered from Braxton Hicks contractions, while trapped with Carly at Jerome Gallery during an earthquake.
On May 11, Nelle fell down a flight of stairs after getting into an argument with Carly. Nelle accused Carly of pushing her. Thankfully the baby came out unscathed.
On July 13, at what was supposed to be his parents wedding, Nelle had cramps and was rushed to the hospital.
On July 16, his parents were married, though it's later revealed the marriage was invalid.
On July 27, Nelle and Michael are involved in a car crash (that Nelle set up in order to kill Michael, although the car was never rigged to crash in the first place) as Michael is setting Nelle up in a sting operation with Detective Chase (in order to take his baby and put Nelle away).
Nelle has no clue that the operation is going on or that Michael is live filming her as they drive before they lose control and the video cuts out. During this Nelle admits she set up Carly (sort of), killed Zachary Grant (her fiancé) and had asked Chase to kill Michael.
Nelle leaves the crash (leaving Michael trapped) as her water breaks in the woods. With the help of Dr. Obrecht, she gives birth to their son.
After the birth of their son, Nelle starts walking, stumbling upon Brad Cooper, whom she passes her son off too, in order to replace his deceased son, Wiley. Nelle also knows that she will lose her baby anyways so she wants Brad and Lucas to raise him. Nelle takes the real baby Wiley and lies to Michael that she "lost the baby".
Brad took the baby home and bonded with him and Lucas. He also meets Lucas' sister, Sam.
On August 2, 2018, Michael and Nelle name their son Jonah. Michael also revealed that he and Nelle were never married.
On August 3, 2018, Michael runs into Brad, Lucas and the baby and he unknowingly holds his own son.
On August 7, Jonah's mom was taken to jail for her numerous crimes against his dad and that side of the family.
On August 17, Jonah spends time with his father and that side of the family unbeknownst to them. Mike also keeps rightfully mistaking Jonah for Michael's son even going so far as to say that he sees Carly in him. Later that day, Brad and Lucas get the news that the birth mother wants the baby back.
On August 21, Brad tells Julian part of the truth of the switch but only that Jonah isn't the birth mother's son, that her son died. He said he came upon a homeless woman who begged him to take her son.
On September 19, Jonah spends time with his biological father and grandma Carly.
On September 20, Jonah is diagnosed with the same heart defect his father and grandfather had when they were babies, he just doesn't need surgery like they did.

In January 2020, Jonah is reunited with his mother Nelle who recently spent time in prison for 2 years for killing her ex-fiancé Zack plus the attempt murder and marriage fraud of his father Michael. Nelle was hired as “Wiley's” nanny to get close to her son Jonah by Brad.
