Separated Irish twins Hassan and Hussein Benhaffaf are to leave hospital.
The five-month-old boys, who were joined from the chest to the pelvis, were separated in a 14-hour operation at London's Great Ormond Street Hospital (Gosh) last month.
The family is due to fly back home to Ireland with the Irish Defence Forces and will arrive back at the Cork University Hospital around lunchtime.
The boys will spend time there before returning to their home nearby with parents Angie and Azzedine Benhaffaf and their older sisters.
In a statement, Mr and Mrs Benhaffaf said they were relieved and happy that their "little fighters" were coming home.
They said: "All the prayers were answered and we thank God that it's all six of us returning home. Hassan and Hussein have gone through so much in their young lives already and now we hope that we can give them the happy future they both deserve.
"We again thank the public for their overwhelming love and support and the media for respecting our privacy and being so sensitive."
About 20 staff, including four anaesthetists and four surgeons, worked in shifts to separate the boys during the complex procedure last month.
The boys' hearts were not joined, but all of their other major organs, including their liver, gut and bladder, were and had to be separated. They have one leg each.
Their parents thanked staff at Gosh, Cork University Maternity Hospital and the University College Hospital, London, where the boys were born on December 2.
