Archie Battersbee died “inadvertently during a prank or experiment that went wrong”, a coroner has concluded.
The two-day inquest had been told Archie's mother, Hollie Dance, found her son unconscious with a ligature over his head at home in Southend, Essex, on April 7 last year.
Doctors later recommended his life support be switched off which his mother and father, Paul Battersbee, fought for several months before the ventilation was withdrawn on August 6.
