Well it you go by tradition and/or the 12 days of Christmas. You don't need to change the decor till the 6th of January.
So the girls can milk this till then.
For spaniards, Christmas is only the beginning. We have festivities until Mage's day (january 6th).
Who would be Melchior, Casper and Balthazar in this little group XD? Balthazar would be Morgan, of course xD
