His Birth and the Heparin Overdose Incident
Thomas Boone was born prematurely via gestational surrogate alongside his twin sister. Within days of their birth, both infants developed a staph infection and were admitted to Cedars-Sinai Medical Center in Los Angeles for treatment.
During their hospitalization in November 2007, Thomas and Zoe were mistakenly given a dose of heparin — a blood-thinning medication — at 1,000 times the intended strength. Instead of receiving 10 units, they were administered 10,000 units due to a medication labeling and handling error.
The overdose occurred on two separate occasions before it was discovered.
Timeline of the Incident
| Date | Event |
| November 8, 2007 | Thomas and Zoe born |

| November 18–19, 2007 | Incorrect heparin dosage administered |
| November 20, 2007 | Error identified |

Fortunately, both twins survived without reported long-term complications.
The Impact on the Quaid Family
The incident deeply affected Dennis Quaid and Kimberly Buffington. Dennis later described it as one of the most frightening experiences of his life.
Instead of remaining silent, the family took legal action and used their public platform to raise awareness about preventable medical errors. Their advocacy focused on:
- Improved medication labeling
- Barcode scanning systems in hospitals
- Stronger safety protocols
- Greater accountability in drug administration
Their efforts contributed to broader national discussions about hospital safety standards.
For Thomas, this means his early medical crisis became part of a larger effort to help protect other families.
Growing Up as Dennis Quaid’s Son
Dennis Quaid has had a long Hollywood career spanning decades, with roles in films such as The Parent Trap, The Day After Tomorrow, and The Rookie. However, when it comes to his younger children, he has consistently emphasized privacy.
Thomas and his twin sister have largely been kept away from regular media exposure. While occasional family photos appear during public outings, there is no active public profile built around Thomas.
Unlike some celebrity children who grow up in constant media visibility, Thomas appears to have been raised with deliberate boundaries between public life and private childhood.
Family Structure and Relationships
Thomas’s family background includes both Hollywood fame and blended family dynamics.
Siblings
- Zoe Grace Quaid – Fraternal twin sister
- Jack Quaid – Half-brother (son of Dennis Quaid and Meg Ryan), now an actor known for The Boys
The significant age gap between Thomas and Jack means they grew up in different media eras. Jack experienced the height of tabloid culture in the 1990s, while Thomas has grown up during the social media age, where privacy strategies are different.
His Parents’ Divorce
Dennis Quaid and Kimberly Buffington filed for divorce in 2012 when Thomas was five years old. After periods of reconciliation, the divorce was finalized in 2018.
Both parents have reportedly maintained co-parenting arrangements focused on stability for their children.
In 2020, Dennis married Laura Savoie. This added another layer to Thomas’s family structure, though public statements suggest efforts toward maintaining a balanced environment.
