As the child of award-winning actor Dennis Quaid and real estate expert Kimberly Buffington, he was born into the public spotlight.

The 2007 Infant Medical Crisis: A Fight for Survival
The story of Thomas Boone Quaid is inextricably linked to one of the most publicized infant medical error incidents in modern American history. Just days after their birth, Thomas Boone Quaid and his sister Zoe Grace were admitted to Cedars-Sinai Medical Center in Los Angeles to treat routine staph infections.
The Heparin Overdose Incident
While receiving treatment in November 2007, both infants were accidentally administered massive doses of the blood-thinning medication heparin. Hospital staff inadvertently gave the newborn twins doses that were 1,000 times higher than the standard prescribed amount for pediatric patients. The severe error occurred because the packaging for adult dosages and infant dosages looked virtually identical, leading to a catastrophic mix-up by hospital staff.
The excessive blood thinner caused severe internal bleeding, putting the lives of both Thomas and Zoe in critical danger. Doctors and specialized medical staff worked around the clock in intensive care to reverse the effects of the drug. After days of intensive monitoring and critical interventions, both infants miraculously survived without long-term physical damage.
