Doctors will be investigating feeding Luke by percutaneous endoscopic gastrostomy, or PEG. This means he will be fed through a tube, put into his stomach using an endoscope.

His 34-year-old mum, Ruth, from Holyhead, who has two other children, said: "They're having a look to establish how well he's doing, and maybe to see if his feeding method can be changed.
"I'm going reluctantly. He doesn ' t respond well to moving.
