Archie Battersbee died Saturday after he was taken off of life support by doctors at the Royal London Hospital.
The 12-year-old had been unresponsive and in a coma since April 7.
His parents, Hollie Dance and Paul Battersbee fought a legal battle for months to extend the life-sustaining treatment for their son but the U.K. Supreme Court in London rejected an appeal last week.
“In sadness, Archie passed at 12:15 pm,” Dance said. “I would just like to say I am the proudest mum in the world. He was such a beautiful little boy.
“He fought right until the very end, and I am so proud to be his mum.”
