'Happy Ending' For Quaid Family After Twins Tragedy

LOS ANGELES, Calif. -- Following a serious hospital mistake, which almost cost his newborn twins their young lives, Dennis Quaid says the entire experience has changed his outlook on life.

"I do have a greater appreciation of life in general," Quaid told People. "If they hadn't made it, it really would have changed my life. But they did survive. So it changed my attitude."

Quaid, 53, and wife Kimberly, 36, welcomed twins Thomas Boone and Zoe Grace into the world on November 8, via a surrogate mother.

Just nine days after being born, the twins were taken to Cedars-Sinai Medical Center for a staph infection. It was then that the newborns were reportedly given a near-fatal overdose - 2,000 times more than needed - of the blood-thinning drug Heparin.

Now that the twins are happy and healthy, Quaid said he and his wife are able to enjoy all that parenthood has to offer.

"It's the greatest thing to hold those kids and see their faces because we had a happy ending. It's great being a normal dad with the normal problems of not having enough hands for both of them," the actor added. "Their progress and their development appears to be completely normal - aside from being a Quaid."
