Devastated parents who lost their baby boy claim hospital staff told them to calm down moments before he died.
Michael Gallagher was born prematurely at 27 weeks on May 24, along with his twin sister Angel.
He was taken to Wythenshawe Hospital in October after struggling with his breathing and doctors found he was suffering with bronchiolitis.
His mum and dad say staff had “plans A, B and C” with Michael set to be moved to the Oxford Road hospital if his condition worsened.
But the plan changed overnight after the staff change with Michael kept in while his blood gas levels became increasingly worrying.
Tragically, the tiny tot later died, the Manchester Evening News reported.
Mum Susannah, 32, said: “He was fighting and fighting and fighting.
"He suffered a bad death and there was nothing I could do, they wouldn't listen to me.
"I believe if my child had been moved to Oxford Road he would be alive. They would have intubated him, they would have given him rest on his little body, given him a little bit of a chance.
"Everything was under control, they had plan B and plan C, when we were still on plan A."
The family say those plans went out of the window after staff changeover for the night shift. Michael had his blood gas levels continuously checked, rising from the normal levels of around 7 to 8.7, then 9.2 and 10 as the evening went on.
At each stage, Michael's parents say they pleaded with medics for their son to be intubated, and for Michael to be moved to Oxford Road.
Susanna says she twice asked a nurse 'can children die from bronchiolitis?' before receiving the reply: "I don't want to answer that question."
She added: "I was looking at Michael and I could see his body moving. I was pointing at him and going 'look!'.
"In 10 to 15 seconds tops she just ripped the blanket off him and they all started working on him.
"I was screaming. My son had just passed away. I couldn't believe it because I couldn't have made it clearer all night - he needs to be moved to Oxford Road.
"Everything was under control. It was just when changeover happened, it went all downhill. To be working on our son and not even take us out of the room, it's very traumatising."
A spokesman for Manchester University NHS Foundation Trust said: “We would again wish to offer our sincere condolences to the family of Michael for their loss. We would welcome their involvement in our investigation into the circumstances around his death.
"An inquest will also be held, so we will be unable to comment further until that has concluded.”
