Santa and Mrs Claus have visited sick children in Crumlin Children's Hospital this afternoon.
Some of the children being treated there might not get home from hospital for Christmas this year.
9-year-old Oisin Slevin met Santa and Mrs. Claus, but he wasn’t letting anyone know what he wanted for Christmas. "That's a secret!" he told 98FM News.
Kerry Lawless from Skerries, who is 12, is hoping to be home for Christmas, but says today is a great way to forget that she’s not well. "It's not your normal routine, because in hospital you have to get up early take your medicine, but today it's more just have fun".
Next week, famous faces will visit the hospital for its yearly Celebrity Ward Walk where children are visited by some of their favourite stars.
