Early Life & Birth Details
Public birth announcements in November 2007 noted that Thomas Boone Quaid arrived first, with time and weight details released at the time, followed minutes later by his twin sister, Zoe Grace. Coverage focused initially on the twins’ arrival and soon after on their health update from the hospital.
The 2007 Heparin Incident—Explained Simply
Shortly after birth, while hospitalized, the twins received an adult-strength concentration of heparin (a blood-thinning medication) instead of the very small pediatric dose normally used to keep IV lines clear. In plain language: the concentration was about 1,000 times stronger than intended for infants.
Clinicians identified the problem, administered the standard reversal care for heparin, and monitored the twins closely. Within weeks, both babies were home and reported to be doing well.
Why the Story Resonated Beyond One Family
The case drew national attention to preventable medical errors—especially look-alike medication vials, storage design, and labeling. In the years that followed, Dennis Quaid used his platform to support patient-safety awareness, helping translate clinical lessons into everyday language so families and hospitals could ask better questions and design safer systems.

Thomas is the son of Dennis Quaid and Kimberly Buffington. His twin sister is Zoe Grace, and his older half-brother is Jack Quaid. Media coverage of the younger twins has been appropriately limited, and this profile respects that by avoiding speculation about schooling, routines, or social media.
