Everything You Need to Know About Katie on YR

It looks like Katie on The Young & The Restless is going to be getting into some trouble, and some newer viewers of the soap might be wondering exactly who this adorable little girl is and who she belongs to. Well, let us fill you in on her history (she’s young, so it’ll be brief!). Played by twins Reese and Kennedy Staib as an infant, the role was later recast in 2016 with Sienna Mercuri , who is still playing Katie today.

Katherine “Katie” Rose Abbott Newman is the daughter of Victoria Newman and Billy Abbott , although there was some question as to the baby’s paternity when Victoria became pregnant. She and Billy were separated and she was dating Stitch Rayburn , but had slept with both men close enough together that she wasn’t sure who was the babydaddy. Victoria was going to have a paternity test run, but learning Stitch was keeping secrets and Billy was still causing trouble made her want nothing to do with either man. The pregnancy was already high risk and she didn’t want the extra stress.

Victoria feared she was going into labor during Nick and Sharon’s wedding, but it was just Braxton-Hicks contractions. Unfortunately, she gave birth in the Jabot Cosmetics parking garage instead after being locked in a storage closet in the building by Stitch’s mom, Maureen Russell. Billy and Stitch found her, but Victoria was already in labor, and the two men worked together to deliver the baby girl who she named after her godmother, Katherine Chancellor.

Stitch was heartbroken when a paternity test revealed that Billy was Katie’s father, but after reconciling with Victoria, moved in and became her stepfather. At the christening, Jack Abbott was named Katie’s godfather and Abby Newman the godmother. After, Nikki Newman nearly dropped the infant while taking pictures, and blamed her Multiple Sclerosis to cover for her drinking. Victoria threatened to keep Nikki from her granddaughter unless she went to rehab.

In 2015, Katie was attending a Halloween party with her brother, Johnny Abbott, at the Newman Towers when a fire broke out. Kevin Fisher and Mariah Copeland helped lead the children to safety and Victoria was very grateful. Then, in 2019, Katie began talking to a friend that everyone in the family assumed was imaginary until the little girl went missing and they found her in a secret room behind a wall at the Newman Ranch! They also found surveillance equipment and they suspected her “friend” was actually J.T. Hellstrom who had been spying on them!

In February 2020, Billy and Victoria sat Katie and Johnny down to tell them that they were breaking up. That summer, Katie had a severe allergic reaction to a bee sting and Billy rushed her to the New Hope Clinic where she was treated by Nate and Elena. Victoria chided herself for not knowing her daughter was allergic to bees and Billy was surprised she didn’t blame him for the incident. That Christmas, Katie and the rest of the family were happy when the charges against Billy (for shooting Chase) were dropped so he could be free to spend the holiday with them.

As 2021 began, Katie and Johnny enjoyed spending time with Billy’s new girlfriend, Lily Winters , which naturally made Victoria jealous. That spring, the kids were also excited to check out their rooms at Billy and Lily’s new apartment. They were slightly less enthusiastic about Victoria’s new beau, Ashland Locke , however. But it was okay, because Katie and her brother were sent off to boarding school so they weren’t around when things went south between Victoria and Ashland.

In June 2024, Katie returned home from boarding school with Johnny and were introduced to their new sister, Claire Howard , who Victoria and Cole Howard had recently discovered had been stolen from them at birth. Katie was upset that they had to live in the tack house after Claire’s Aunt Jordan had burned down their real home, and angrily stormed off.
