COMEDIAN Brendan O'Carroll and over 30 Irish celebrities treated sick children in Crumlin to a carol sing song yesterday.
COMEDIAN Brendan O'Carroll says he understands the worry parents go through when they have a sick child.
The 'Mrs Brown's Boys' star, a father of three, said that visiting young patients in the build-up to Christmas makes him appreciate how lucky he is his family are healthy.
The award-winning actor was speaking as he spread some festive cheer in the wards of Our Lady's Children's Hospital in Crumlin yesterday.
He was joined by a number of well-known faces as part of the annual star-studded Heinz Celebrity Ward Walk.
O'Carroll flew back to Ireland with his wife Jenny for the occasion and told the Irish Independent that his Christmas "would not be complete without the visit".
"The first time we did it we were terrified, but it's a joyous day. You leave the ward walking on air because the resilience of these children is heart-warming."
Singer Mary Byrne told the Irish Independent that the event helps her to realise how blessed she is that her daughter Debra has her health.
"I can't even begin to understand the fear and sadness these parents often feel and my heart goes out to them. I'm a lucky woman," she said.
"A visit like this brings you back down to reality and makes you realise that there are people in the wards here that will never have what you have."
Stylist Lisa Fitzpatrick added: "It's a very difficult time for families, especially the mums because they spend a lot of time away from their other children to stay here."
'The Voice' coach Bressie was extremely emotional after spending time in the Intensive Care Unit and Burns Unit.
"The staff are just incredible, they have a huge job."
The Ward Walk is held in association with Heinz, who gave a donation of an undisclosed amount to the Dublin hospital.
Four-year-old Oliver Bacon, from Co Wexford, was among the lucky ones to meet O'Carroll.
Oliver, who is the grandson of economist Peter Bacon, has cystic fibrosis and is a regular patient at the hospital.
"He's in and out a lot," said mother Hazel Bacon. "It's very difficult, especially for the mothers, but we're really made feel at home."
