Toddler Callum Barrett has finally returned home after spending three weeks in hospital and is doing well.

The little boy who is allergic to life because of a rare immune disorder has had four operations in 10 days.

He is now settling back in to home life in Moredon after his spell at the Bristol Children's Hospital and is even preparing to go on a family holiday to Wey-mouth next week.

Callum's mum Michelle, 23, said: "He's great now and seems to be getting back to his happy little self again."

The toddler will turn two on October 14. He suffers from hypogammaglobulinemia, which breaks down his natural defences against everyday life.

During his stay in hospital, he had a bowel biopsy and a gastrotomy a procedure used to insert a feeding tube through the skin into the stomach.

Doctors also cut open his stomach to attempt to shrink his oesophagus to combat his excessive vomiting. A week later, he had to undergo another operation on his large bowel after his body continued to reject nutrients fed via a tube.

Michelle said: "He has still got swelling inside his tummy after the operations and is having problems walking due to the catheter he wore for a while.

"He is having to learn how to eat all over again because he had the reflux for so long which made him sick all the time.

"It's a bit like feeding a newborn baby and trying to wean them on to solids."

Michelle's partner, Darren May, 27, said Callum's bowel was acting against his own body, creating further complications. "His bowel was trying to swallow itself," he said. "It's a bit like what happens when you take your sock off and it goes inside out.

"His bowels had been handled so much during all the operations that they weren't working properly."

Callum's feeding tube in his stomach will administer vital nutrients overnight and once again during the day but Michelle is hopeful his appetite will improve with time.

"His eating has been on and off because it is still so new to him," she said. "A few days ago he wanted two bowlfuls of pureed food for breakfast and dinner but yesterday he had gone off it again.

Callum's six-year-old sister Sophie is more thrilled than anyone to have her little playmate back again.

She had spent the last few days preparing a huge welcome home banner for her little brother.

Callum, who came out of hospital on Sunday afternoon, will still need regular blood infusions to top up his level of white blood cells that boost the immune system.

His family are waiting to be told the date for his first check-up.

Michelle, Darren, Callum and Sophie will be joined by Callum's grandparents Jill and Pete and Michelle's sister, Melanie on next week's holiday.

Michelle, who is expecting a baby girl in November, added: "Darren thinks the baby will arrive while we are on holiday but that would be four weeks early.

"I'm just hoping for a relaxing time away."

Callum's rare condition affects one in 10,000 people. It means that his immune system cannot cope with everyday life.

Since April he has worn a feeding tube 24 hours a day to administer nutrients. This was first inserted through his nose but now enters skin near his stomach.

He will probably need blood infusions every few weeks for the rest of his life.
