His colleagues from North Wales Police were also quickly on scene, said the dad, adding that he and his wife were grateful for everyone’s support, including NHS staff at Wrexham Maelor Hospital and Alder Hey, who “have been fantastic”.
Smith said it was a “worrying time”, explaining that what happened to Rupert “can happen at any time” due to his condition.
He said: “It’s such a rare condition and there is only so much they [the NHS] can do.
“We have got to go to the US to get treatment.”
His wife added: “We just need to save his life… please, please help save our baby boy.”
The couple, who have two other sons, aged four and five, have launched a charity called Rupert’s Rainbow to raise funds for Rupert to take part in clinical trials in the US as well as fund research into the rare condition.
Siobhan Smith, an NHS pharmacy technician, and her husband said they have raised about £65,000 so far.
“The only potential for a cure lies in ongoing research and clinical developments in the United States, which require significant private funding,” they said.
