santa Claus had lots of posting to do for the coming days as he replied to children who posted letters to him.
Father Christmas was in the GPO in Dublin with bundles and bundles of postcards containing his kindly replies for each and every child.
Children visiting the postal headquarters in O'Connell Street were delighted to be asked to help Santa to post all his replies.
"Santa has replied to all 140,000 boys and girls who posted him letters this year," said a spokeswoman for An Post.
"Post office staff started to help Santa Claus 30 years ago to post his replies. The numbers of children posting letters to Santa in An Post letter boxes has been steadily increasing since then.
"Each child gets a reply with their name and address on the front of each card," she said.
An Post staff are happy to deliver letters to the North Pole from children throughout the country.
As well as staff making sure Santa gets each letter, workers in the Rehab workshop in Mountmellick also help to ensure Santa's post gets priority treatment, she said. Santa wrote his reply cards in Irish and English and told the children that Mrs Claus was working hard too.
An Post also assured every child that wrote a letter to Santa but did not post it, that Santa saw those letters too.
