In our house the presents were all from Santa, and that's what we do here. In fact I never really thought about doing it any different. I don't think I need to take any of the credit, they will only be little enough to believe in the magic for such a short time.

I too go with DS to buy a present for the wishing tree. We did too when I was little. I don't think I actually put two and two together on that until I didn't believe in Santa any more, although I did question why Santa didn't come to poor people.
