A four-year-old boy who just learned to dial 911 is being credited with saving his diabetic aunt`s life. Relatives say he was home with his aunt, Cynthia Newell earlier this month and called the emergency number for help when he could NOT wake her up. His mother, Teri Demont, says she had just taught him to dial for help and was surprised he successfully did so since he kept referring to the emergency number as 991 or 901. Demont says her son stayed on the phone with dispatchers until police came to the house, then let them inside. Newell is diabetic and had a slightly enlarged heart and stiffening of the heart valves. She was taken to Newport Hospital and released a few days later.
