Most children dream of tucking into a slice of birthday cake, delving into bags of sweets, or scoffing an ice cream on a hot day.
But for Finlay Doolan the luxury of sweets - and indeed all food - must remain a dream.
The six-year-old suffers from a rare and incurable condition called eosinophilic esophagitis and eosinophilic colitis which makes him allergic to everything he eats and means he must rely on a drip to provide him with nutrients.
Diagnosed three years ago, Finlay is unable to eat any food because it aggravates his throat and colon and makes him sick. The immune is so rare it affects as few as one in 10,000 people.
Both conditions are caused by the body producing too many of a type of white blood cell in his oesophagus and colon.
