Jackiey revealed that the late 27-year-old made the heart-wrenching plea just days before she lost her battle to cervical cancer on Mother's Day.
"She wanted me to put a pillow over her head," the Daily Star quoted Jackiey as telling OK! magazine.
"I really didn't want to see her go that way. I thought: 'I don't want to have to suffocate her without anyone knowing.'
"If she was on a machine, we'd have to turn it off, but when you've got cancer you don't have a machine," she added.
The grieving mum further revealed that she had been reading her own Mother's Day card from Jade at the same time when her cancer-strciken girl left her forever.
She added: "I sat by her bed and I saw this envelope with 'Mum' written on it. I got it down and I ripped it open, thinking the card was from the boys to their mum and I could read it to her.
"And by the time I'd finished reading it, she had died. Then I realised it was to me from Jade. Jack had put a pen in her hand so he could help her write it. On her last breath, as I was reading it, she flickered. She had heard me reading it."
