Not a good idea for a 2 year old.
Just for future reference.
Unless, of course, you like listening to an upset child who doesn't understand the whole "one chocolate a day until Christmas" thing.
(He is, fortunately, more accepting of the idea now - but still, not really getting the whole concept.)
In other news, the Christmas decorations are up, some Christmas pictures are taken, and gingerbread cookies are cooling in the kitchen!
