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.
Sherwyn's mother, former schoolteacher Amanda Sarabi, 35, said: "At first we just thought it was normal behaviour, then one day when we were in the GP's office, he was looking at a map on the wall and started pointing out countries he recognised.
"The doctor was amazed and said he'd never seen anything like it."
We've taken him to see a couple of psychologists who have both said he is gifted."
British Mensa's gifted child consultant Lyn Kendall identified behaviours that a gifted child may display.
She said a child with unusual hobbies and interests, who learns easily or who has an in-depth knowledge of certain subjects may also be gifted, according to the checklist.
A spokeswoman for the National Association for Gifted Children said that it is important for a child with high learning potential to get the appropriate help and support along the way.
She added, what a lot of parents don't realise is that this is only the beginning of the journey.
