The RAF Hercules was used to transfer the baby during the storms

The three-week-old, whose parents live in Bridgend, underwent specialist emergency treatment at a children's hospital in Glasgow after the 350-mile trip earlier this month.

A spokesman for the Royal Hospital for Sick Children, Yorkhill, Glasgow, said the baby, who was born with a heart and lung condition, was now "doing well" and was fit enough to return.

The harsh weather conditions meant an RAF rescue helicopter could not be used for transferring the child, who was five days old at the time.

The hospital spokesman said the family was "relieved to be going home".

The boy was born with pulmonary hyper-tension and has now had heart lung bypass treatment. His parents have been at his bedside throughout the treatment.

"His parents would like to thank everyone who has been involved in the care that their son has received," he said.

The boy has gone from being in a serious condition to stable.

'Doing well'

"Initially he had a lot of equipment attached to him but he has recovered and is doing well on his own."

He said the baby would still require hospital treatment in Wales.

The airlift took place on 13 January, after there was not enough room for the boy at Great Ormond Street Children's Hospital, London.

Instead, an RAF Tristar flew two doctors and a nurse from Glasgow to Brize Norton in Oxfordshire where they were transferred to a Hercules plane before going on to Cardiff.

They were then driven by Singleton Hospital, Swansea, where they spent hours stabilising the boy.

The medical team and the baby were then all flown to Glasgow.
