Who is Katie Newman on The Young and the Restless?

Victoria Newman and Billy Abbott are the parents of Katherine "Katie" Rose Abbott Newman in The Young and the Restless. The identity of the father was not entirely clear when Victoria became pregnant. Victoria was dating Stitch Rayburn while she and Billy were no longer together.

She had been with both men at the same time. This made it difficult to determine who Katie's father was. Victoria considered getting a paternity test, but decided against it because Stitch was keeping secrets and Billy was causing problems. Victoria's pregnancy was already high-risk, and she wanted to avoid additional stress.

Who helped deliver Victoria's baby?

Victoria thought she was going into labor at Nick and Sharon's wedding in The Young and the Restless. However, they turned out to be Braxton-Hicks contractions. Later, she unexpectedly gave birth in Jabot Cosmetics' parking garage.

This occurred after Maureen Russell, Stitch's mother, locked her in a storage closet. When Billy and Stitch arrived, she was already in labor. They worked together to deliver the baby girl, whom Victoria named after her godmother, Katherine Chancellor.

Stitch was devastated to learn that Billy was Katie's father following the paternity test. He made up with Victoria and despite this, moved in with her, and started a family with Katie. Jack Abbott was named Katie's godfather and Abby Newman her godmother at her christening in The Young and the Restless.

Nikki Newman nearly dropped Katie while taking pictures during a ceremony. She was drinking and blamed her Multiple Sclerosis for the incident. Victoria, angered by this, vowed to keep Nikki away from Katie until she entered a rehab facility. Victoria wanted to protect her daughter from negative influences.
