Who was the youngest person that was helped by St Philip from heaven?

A four year old boy. In July 1597, just over two years after the death and burial of St Philip, this young boy was suffering from a terrible fever. His condition got so bad that he could neither speak nor move for several days. When his mother despaired of his remaining alive, she laid on his head a piece of cloth of St Philip's. The effect and cure were immediate. The joy of his parents were indescribable.
