Love that name! He should be proud of the link to this saint as his patron.
The parish Christmas party is scheduled for Saturday evening after Mass for the Immaculate Conception. In the past, Santa would pay a visit and bring gifts to the kids. I made some changes this year. I plan to gather the children around and read them The (real) Christmas Story. This will be followed by the story of St. Nicholas and the arrival of Santa with simple gifts for the kids. Over the next few years, we will reshape Santa's costume into that of St. Nicholas :-)
We won't be able to celebrate Holy Nicholas' feast until the 16th this year because of scheduling conflicts with the St. Nicholas parish, but it will be a good time. The little ones are always impressed when St. Nicholas arrives in his beautiful red vestments and sparkling miter. I wrote a little post in my blog last year about the experience for #1 Grandson. LOL!
