Boy, four, stabbed himself in heart while making sandwich
"The inquest heard the boy had always previously asked his mother for food if he was hungry.
But instead, on Saturday, July 2 last year, he climbed on a worktop, took a knife, described as a pairing knife, from a kitchen block and began to make a sandwich.
He had laid out bread, meat and salad cream but then somehow fell, with the knife puncturing his chest through his rib cage and into his heart and a lung. "
My heart goes out to them :(
