Another seven babies were born at Valley Baptist Medical Center in Brownsville.
Parents told Action 4 News that they TMre excited their children were born on such a special day.

Born weighing 6 pounds and 11 ounces, Dominic is one of six Leap Year babies born at Valley Baptist in Harlignen.
I've been hearing different things," Valencia said. I can celebrate it on the 28th or the 1st. The baby's not gonna have a birthday for four years but, we'll see."
