When my kids were little we had a Christmas tradition that they just loved. And now my daughter is passing this tradition along to her daughter. Since the kids like it so much, I thought I'd pass it along.
1. Go to the store and buy a bag of chocolate. It can be any kind of individually wrapped Christmas chocolate, but make sure it is a brand that you don't buy for any other Christmas treat. I usually used Palmer's Christmas balls.
2. Put bag of chocolate in freezer and get it frozen.
3. When the kids are in another room lay a piece of chocolate on the table or counter. Always leave it in the same spot.
4. Ring a bell really loud, then quickly hide the bell.
5. When the kids run out you explain that the elves were here and left them a chocolate treat. It's straight from the North Pole cause it is cold.
It doesn't take but one time ringing that bell and they know what it's for and where the chocolate will be. My daughter also pointed out that if you watch Christmas specials and see the elves with bells on their shoes to point that out to the kids and that is why they hear the bells. I never did that, but it is a good idea. I usually only did this once a day every day until Christmas. It really helps build up the excitement for Christmas (as if they need any help with that) and it is a lot of fun for you and the kids.
It is nice to see Christmas traditions being passed down from generation to generation. Even if it is a silly little thing. It brings excitement and fun.
