Six-year-old Peruvian girl Milagros Cerron blows out her birthday candle flanked by Lima Mayor Luis Castaneda (L) and her doctor, Luis Rubio, during her birthday ceremony at Lima's City Hall, April 27, 2010. Milagros Cerron, known as the 'Little Mermaid' because of a rare birth defect in which her legs are joined together, is making good progress after being operated three times in the last five years in Peru, doctor Rubio said.
