Hi, WC. I am a parent to two daughters, age 11 and 8; and part-time mom to a part-time daughter and part-time son, age 10 and 8.
My husband was raised in an ethnic German family whose cultural celebrations don't have Santa Clause or the Easter Bunny; and I am an adult convert to Christianity so Santa and the Easter Bunny don't have any childhood associations for me, either.
At Christmas time we prepare by having an advent wreath, preparing a creche, and processing the creche figures of Mary and Joseph through the house (not to mention stirring prayers into our figgy pudding on "Stir-up Sunday", making cookies and mincemeat, dancing in Nutcracker and practicing for the Sunday School Pageant. During Christmas -- which lasts for twelve days -- we attend the pageant, family prayers and gifts with my husband's family, midnight mass, and Christmas morning services, three or more Christmas dinners, and copious visiting with friends.
During Easter we attend Maunday Thursday services with Agape meal, foot-washing and stripping the altar. On Good Friday we fast, make bread, bread and attend the Great and Holy Vigil at midnight. On Easter we attend Sunrise services, communal breakfast at church, Bible-study and Easter Eucharist, and family dinner.
Where would we fit in such trivialities as Santa and the Bunny? They are clearly works of super-rogation, as it were. My daughters have been known to speak pityingly of their poor secular friends who get only one day of Christmas, and have never been to a Maundy. They don't feel left out in the least.
