Logan Donegan, aged 23 months, was born with a rare disorder called gastroschisis, which affects about three babies in every 10,000 births. Logan's bowels were growing outside his body, meaning he could be fed only by protein drip.
Surgeons at Birmingham Children's Hospital transplanted Logan's intestines after seven surgeries failed to correct the problem.
After the success of this transplant, Logan has started eating Marmite on slices of bread. His mother Rhian is delighted with her son's progress even though she does not like Marmite.
"I can't stand the stuff but Logan loves it. It's fantastic to be able to feed him for the first time," she said.
