The youngster's devastated mother Karen confirmed the news to the Irish Independent.

Séan, known by friends as "Lil Red", was treated for a cough and chest infection at the city's Temple Street Hospital. 

"We don't really know what happened. He had a bad cough and chest infection so I brought him to the GP and he was prescribed antibiotics in case it developed into pneumonia," his mother told the news outlet.

"I said to my husband that Séan wasn't looking well but before I got a chance to bring him back to the doctor he was gone. It was so sudden. We will get answers eventually."
