Ruth, who is separated from her husband and has two other children, Andrew, 12 and Sophie, seven, told the Daily Post she felt she had "betrayed" her son by taking him to Alder Hey.
She said: "I brought him up here to help and they are going to try to let him die. How can they destroy a family and send him to his grave? This is absolutely sick. He has a quality of life. They won't win with my little boy."
The baby boy was due to return to North Wales earlier this week but Ysbyty Gwynedd claimed it no longer had the specialist staff required to treat him.
