How Old Is Thomas Boone Quaid in 2026?
He turned 18 in November 2025. So he is an adult now. That milestone matters because he can now decide how public he wants to be.
Thomas Boone Quaid’s Birth and Early Life
Thomas arrived on November 8, 2007. His twin sister Zoe followed just minutes later. The babies came four weeks early but left the hospital after three days. At first, life at home looked normal.
Then trouble started. Around day eleven, Kimberly noticed irritation on Thomas’s belly button and on one of Zoe’s fingers. Their doctor sent them to Cedars-Sinai Medical Center. Tests showed a staph infection, so the twins needed IV antibiotics.
Born Through a Gestational Carrier
The twins were born through a gestational carrier. People often call this a surrogate. Dennis and Kimberly are the biological parents. They had waited a long time for this moment, so the arrival felt huge for them.
The Heparin Overdose That Nearly Took Thomas and Zoe

While in the hospital, both babies received a huge dose of heparin. This drug thins the blood. Dennis Quaid later said the twins got 10,000 units instead of the 10 units meant for infants. That mix-up was about 1,000 times too strong. The vials looked alike, and that confusion played a key role.
Doctors spotted the mistake and gave a reversal drug called protamine sulfate. Both babies recovered fully. Cedars-Sinai admitted the error was preventable. The family later took legal action involving Baxter Healthcare, the maker of the heparin products. You can read a clinical review of such errors at the AHRQ Patient Safety Network.
Why This Medication Error Mattered for Patient Safety
Think of two bottles that look nearly the same on a crowded shelf. One wrong grab changes everything. That is why drug labeling and packaging matter so much. The Quaid case showed that mistakes often come from weak systems and not just one person.
| Safety Lesson | What It Means for Families |
| Look-alike packaging causes errors | Ask the nurse to confirm the drug name |
| Dose size matters in babies | Ask why that dose fits your child’s weight |
| Teams share responsibility | Speak up when something feels off |
Thomas Boone Quaid’s Parents: Dennis Quaid and Kimberly Buffington
Dennis and Kimberly married in 2004. They split in 2016, and the 2018 divorce ended the marriage. Even so, both parents have stayed involved in raising the twins. Kimberly works outside the entertainment spotlight and keeps her life private. Dennis has spoken about fatherhood in many interviews.
The two also stood together on May 14, 2008. They gave congressional testimony to the U.S. House Committee on Oversight and Government Reform. They described what happened to their babies and asked for stronger safeguards. Their voices carried weight because they spoke as scared parents first.
The Quaid Foundation and Parental Advocacy
After the scare, Dennis launched the Quaid Foundation. Its goal is to raise awareness about preventable medical errors. Think of it as a family pain turned into public good. Many parents have learned to ask better questions at the hospital because of this work.
