Eight babies born to a mother in Southern California - only the second live-born set of octuplets in the world - were in stable condition and breathing on their own, doctors said Tuesday. Dr. Mandhir Gupta, a neonatologist at Kaiser Permanente Bellflower Medical Center, told ABC television that the babies "are doing actually very, very well." Two of the newborns were initially put on ventilators, but their breathing tubes have been removed. "Only three babies need some sort of oxygen through the nose right now but they are breathing on their own," Gupta said on "Good Morning America." The world's first live octuplets were born in March 1967 in Mexico City, but all died within 14 hours, according to Encyclopedia Britannica. The United States' first live octuplets were born in Houston in 1998, three months premature. The tiniest died a week after the birth. The surviving siblings turned 10 in December.
