Connie Yates reduced a courtroom to tears while accusing Great Ormond Street of wasting so much time her little boy no longer had hope.
'We are so sorry we couldn't save you,' she said.
'We had the chance but we weren't allowed. Sweet dreams baby. Sleep tight our beautiful little boy.'
Even the judge appeared to wipe away a tear when Miss Yates said her 'warrior' son – pictured above before he became ill – would not live to see his first birthday next week.
Charlie's life-support system will be withdrawn after his parents reluctantly gave up their eight-month crusade to win treatment for his extremely rare and devastating muscle-wasting condition.
As relatives in the public gallery sobbed, Miss Yates, 31, said her son's brain was never as damaged as the hospital claimed.
But a new scan last week revealed his muscles had deteriorated so much, the experimental treatment being offered by a doctor in the United States would now be hopeless.
