Sherwyn Sarabi's parents believe they may have a genius on their hands - aged just two. He can identify all the countries of the world, can read, use an iPad and has amazed doctors and child psychologists with his intelligence. Sherwyn, of East End Crescent, Royston, can count to 200, explain volcanoes and shooting stars, and describe all major body organs and their functions. The gifted toddler, who turns three in September, said his first words at ten months and could name all 2D and 3D shapes aged 18 months.
