Even with a famous father, Thomas keeps almost no public pictures or social media pages. He likes to stay private and live like other teenagers his age.
His full name is Thomas Boone Quaid. He shares his birthday and early memories with his twin. The family has always worked hard to give him a normal childhood full of school, friends, and quiet times at home.

Early Life and How He Was Born
Thomas Boone Quaid and his twin sister Zoe Grace were born with the help of a gestational surrogate. This means another woman carried the babies for the parents. Dennis Quaid and Kimberly Buffington had tried for a long time to have children. They faced several sad losses before the twins arrived. The birth felt like a special gift after years of waiting and hope.
Thomas was the first to arrive at 8:26 in the morning. He weighed six pounds and twelve ounces. Zoe Grace came two minutes later at 8:28. She weighed five pounds and nine ounces. They were born at St. John’s Health Center in Santa Monica. The parents were full of joy. They held their long-awaited babies and felt thankful for the new chapter in their lives. The family celebrated this happy moment after so many hard times. Thomas and Zoe spent their first days safe with their parents and nurses who cared for them carefully.
The Heparin Overdose That Happened Soon After Birth
Only a short time after Thomas and Zoe came home, they needed to go back to the hospital. They had a common newborn infection called staph. Doctors at Cedars-Sinai Medical Center put them on medicine through small tubes. Something went very wrong with the medicine called heparin. Heparin is a blood thinner that keeps blood from clotting in the tubes. The twins got a dose that was one thousand times stronger than it should have been. The mistake happened two times in the same day.
The strong medicine came from adult bottles that were put in the same place as the baby bottles. Nurses did not catch the difference right away. The babies started to bleed from the places where the tubes went into their skin. Doctors acted fast and gave them another medicine to stop the effects of the heparin. Thomas and Zoe stayed in the intensive care unit for about two weeks. The whole family waited and prayed. In the end both babies got better. Doctors said they had no lasting damage. This was a huge relief for everyone.
Dennis and Kimberly later talked about the event so other parents would know about hospital safety. They started the Quaid Foundation to teach hospitals how to avoid the same kind of mistakes. The experience made the family even more careful about privacy and health. It also showed how strong the twins were from the very start of their lives.
Family Background and His Parents
Thomas Boone Quaid belongs to a family that mixes movie fame with everyday Texas values. His father Dennis Quaid was born in 1954 in Houston, Texas. Dennis became a successful actor over many years. People know him from movies such as The Parent Trap, The Day After Tomorrow, and The Rookie. He has always tried to be a present father even while working long hours on film sets.
His mother Kimberly Buffington works in real estate. She comes from Texas and knows how to build strong homes for families. She focused her energy on giving Thomas and Zoe a steady and loving place to grow. Dennis and Kimberly got married on July 4, 2004, at a ranch in Montana. They were happy and later welcomed the twins. Over the years the marriage faced hard times. They separated more than once and finally divorced in 2018.

Both still show up for important days like birthdays and school events.
Siblings and How the Blended Family Works

Jack is an actor himself and is known for roles in the show The Boys and other films. The age difference is large, yet the brothers stay in touch and support one another.
The family became blended when Dennis married Laura Savoie in 2020. Laura has become part of the circle of care around Thomas and Zoe. The parents and step-parents try to keep life calm and respectful. They attend graduations and other milestones together when they can. Age gaps and different careers do not stop them from sharing love and good times. Thomas grows up knowing he has many people who care about him.

Instead he focuses on school, family, and the simple things that make a normal life good. This quiet strength comes from the love and lessons he received at home.
Education and the Move Into Adult Life
Thomas went to high school in the Los Angeles area. In 2026 he finished his senior year and received his diploma. Both of his parents came to the graduation ceremony. They sat with pride and watched him walk across the stage. Dennis even spoke to the graduating class that day. The event was a happy family moment after years of co-parenting.
After high school Thomas plans to go to the University of Colorado Boulder. College will be a big new step. He will live more independently while still knowing his family stands behind him. The year 2026 has brought many changes. Zoe finished school a little earlier in May, and Thomas followed in early June. These dates marked the end of child-support payments that had been part of the divorce agreement. The family handled the legal details while still celebrating the children’s success. Thomas now looks ahead to classes, new friends, and the freedom of young adulthood.
Living Away From Cameras and Staying Private
The Quaid family decided early that Thomas and Zoe should have a normal childhood. They did not want the twins to grow up in constant camera flashes or news stories. This choice became even stronger after the hospital scare. The parents wanted safety, quiet days, and regular school life more than public attention.

Many children of famous actors feel pressure to be stars themselves. Thomas’s parents protected him from that pressure. He can decide later if he wants a public life or a private one.
