The sister of Guardian Angels founder Curtis Sliwa gave birth to twins Tuesday, three days shy of her 57th birthday.
Aleta St. James, who became pregnant by in-vitro fertilization, and her newborn son and daughter are doing well, said Maria Sliwa, the babies' aunt.
Francesca, who weighs 5 pounds, 12 ounces, and brother Gian, who is 5 pounds, 3 ounces, were delivered by Caesarean section in Mount Sinai Medical Center. They are in excellent health, said Dr. Jonathan Scher, who delivered the babies.
St. James, a motivational speaker who helped her brother set up the crime-fighting Guardian Angels group in the 1970s, said earlier this week that it is never too late to become a mother. "You are never too old," she said. "It's just in your mind."
