DCs were stupidly excited as we put their shoes by the fire this evening (along with carrots for Schimmel - Sinterklaas' horse - and een biertje for Sint :o ) and we sang some Sint songs (have realised this year quite how embarrassed DS1 - 10yo - is about this aspect!). In the morning they will wake to find sweeties and pepernoten (spice biscuits) in their shoes.
So we do this every day for the next 5 days (each day getting something a little bigger than the day before) and then on 5th December we wait until evening and there will be a knock at the door. DCs will open door to find either a sackful of presents or an empty sack!
It's weird because the Advent calendars get somewhat by-passed for the first 5 days of December and the DCs confuse the rest of the kids at school by telling them Sint is stopping by that evening!!
