Toddler Callum Barrett, who suffers from a rare immune disorder, could be home from hospital this weekend.

Callum has had four operations in 10 days due to the illness that renders him allergic to life.

The Moredon youngster, who will be two on October 14, took his first steps after being bedridden for two weeks at Bristol Children's Hospital.

Callum suffers from hypogammaglobulinemia, which breaks down his natural defences against everyday life.

He has had a bowel biopsy and a gastrotomy, a procedure used to insert a feeding tube through the skin into the stomach.

On the same day, doctors at Bristol Children's Hospital cut open his stomach in an attempt to shrink his oesophagus to combat his excessive vomiting.

It was thought the operations were successful, but last week doctors decided to operate on his large bowel after his body continued to reject nutrients fed via a tube.

Callum's grandmother, Jill Barrett, said she was thrilled the final operation had been a success.

"There are no drips, no painkillers, and the only tube in Callum now is his feeding tube," she said.

"Callum has eaten two rusks with water, the first breakfast he has had for ages, and he's been drinking from his bottle. When he took his first steps to the playroom he looked like a drunk little man. He seems so much happier."

Callum's mum Michelle, 23, and her partner Darren May, 27, have been keeping a constant vigil at his hospital bedside.

Callum's six-year-old sister, Sophie, has been preparing a huge banner for her brother's homecoming.
