The second twin, a girl, was born 12:16 a.m. Monday, weighing in at 4 pounds 10 ounces, and about 16 inches.
The twins' mother, Maria Esperanza Flores Rios, had a due date of January 27 but was scheduled for a C-section January 10 due to her high-risk pregnancy.
As the first babies born in the New Year, the Flores twins will get over $3,000 dollars in brand new baby gear, donated by local community organizations.

According to the Daily Mail, which also picked up on the Delano twins, there were four of them in the US a year ago. "The whole family feels humbled and blessed and excited", the spokesman shared.
