We go to church on the 24th and we celebrate Christmas day with our kids and their spouses. We exchange gifts...but we write a little poem with each gift. The poem can be funny or not.
My husband is from the Netherlands where he celebrated Sinterklaas (Saint Nicholas) with gifts and poems and I am from Belgium where I celebrated Christmas and no poems. So when we moved to Canada, we decided to combine the two with Christmas. We wanted our kids to have some heritage from our origins. On top of it, it gives more meaning to your gift.
Have a Merry Christmas!
