Shweta Verma, whose six-month-old son Saurish survived after his pushchair fell off a platform into the path of a train, has described him as the "world's luckiest baby".

Shweta Verma, a 29-year-old dentist from Melbourne, said that "everything went blank" when she realised that her six-month-old son Saurish was rolling away from her after she took her hands off the handles of the pushchair for a few seconds.

In her first comments on the Oct 15 incident, she spoke of how she had desperately tried to run after the pushchair before it toppled over the edge of the platform at Ashburton station with the train approaching. Footage of the horrific moment Saurish disappeared off the platform was captured on the station's CCTV and has been watched around the world.

Mrs Verma told Woman's Day magazine: "It was a life and death fear – I thought I'd lost my child, who I love more than anyone or anything else – but then the next moment, all I could think was how to find him and see how he was."

Aaron Dryden, an 18-year-old student, tried to flag down the train by catching the driver's attention. After the train came to a stop, he ran with Mrs Verma to the front of the train. They then realised from the cries coming from the tracks below that Saurish was alive.

"The first feeling was, 'My baby is alive!' It was the most incredible moment I have ever experienced," said Mrs Verma. Amazingly Saurish only suffered a bump to his head. His mother told the television programme A Current Affair her son was the "world's luckiest baby".
