I found a lovely website where you can read up on Christmas traditions worldwide and according to this website, tradition is Ireland is as follows:
Christmas in Ireland lasts from Christmas Eve to the feast of the Epiphany on January 6, which is referred to as Little Christmas. Ireland's Christmas is more religious than a time of fun.
Lighted candles are placed in windows on Christmas Eve, as a guide that Joseph and Mary might be looking for shelter. The candles are usually red in color, and decorated with sprigs of holly.
Irish women bake a seed cake for each person in the house. They also make three puddings, one for each day of the Epiphany such as Christmas, New Year's Day and the Twelfth Night.
After the Christmas evening meal, bread and milk are left out and the door unlatched as a symbol of hospitality.
St Stephen's Day, the day after Christmas, is almost as important, with football matches and meetings going on. For children, the Wren Boys Procession is their big event. Boys go from door to door with a fake wren on a stick, singing, with violins, accordions, harmonicas and horns to accompany them. The reason for the ceremony is to ask for money 'for the starving wren', that is, for their own pockets.
Children often put out Christmas sacks instead of stockings.
It is tradition to leave mince pies and a bottle of Guinness out as a snack for Santa.
Never came across a seed cake and I never saw any bread and milk left outside.....but it sounds nice anyway :-)
Who got their own traditions?? I for example open a lovely bottle of champagne in the morning when I start the preps for the dinner...and by the time dinner is served......I have a big smile on my face ...
