WHILE other toddlers are content to sit in front of the television, Sherwyn Sarabi prefers to search for his favourite shows online.
That's when he's not too busy studying his inflatable globe or favourite encyclopaedia, of course.
The extraordinary two-year-old can identify all 195 independent sovereign states on a map of the world — and even match them with their national flags.
He can also read up to 500 words, describe all major body organs and their functions, count to 200, identify shapes and explain volcanoes and shooting stars.
Sherwyn, who goes to nursery two afternoons a week, said his first words at ten months and was playing on an iPhone as though he 'had one for years' by 18 months.
His abilities have stunned experts, as well as his parents Amanda, 35, and Daroud, 36.
Mrs Sarabi said: "He just loves to learn - he recently woke me up at 3am telling me all about Sir Isaac Newton and how he discovered gravity. We can't go anywhere with him without him asking "Why? Why? Why?" about things going on around him."
The former teacher, who has given up work to care for her construction worker husband as he recovers from a serious car accident, said they believed their son was exhibiting normal behaviour until a trip to the doctor earlier this year.
She said: "He was looking at a map on the wall and started pointing out countries he recognised. The doctor said he'd never seen anything like it.
"We then took Sherwyn to a consultant paediatrician who thought he was of above average intelligence."
The family, from Royston, South Yorkshire, sought advice from educational psychologist Dr Peter Congdon, who runs the Gifted Children's Information Centre in Solihull, West Midlands.
Dr Congdon has offered to assess Sherwyn's IQ once he turns three next month, saying: "I don't like to see children under three because it is only then that you can conduct a comprehensive assessment."
Sherwyn's parents hope he can start school sooner than his peers to stop him getting bored — and he has already been offered a scholarship to a local independent school.
