A video of a toddler identifying all the countries on a map has been posted online.

Aanav Jayakar, who is 18 months old, correctly points to the country his mother asks him to identify on both coloured and black and white maps.

His mother Dr Bijal Jayakar, who filmed the video, explained that they first discovered Aanav's skill when her husband starting talking to him about their home city of Delhi.

She told The Daily Telegraph: "I said, 'Delhi is the capital of India' and he remembered. So I did China and France. The common ones. We started off with easy capitals and in six weeks, he knew 53 of them."
