P.F.
My son is 10 and in fifth grade. I know he knows the real truth but we still pretend and he still pretends for us. It is a still very fun. He has mailed and addressed his letter to Santa and rode his own bike to the post office to mail it. In reality it seems silly but it is the fun of the season. I would NEVER come right out and admit it and I don't think he would either. partly I think because he is an only child if he admits it the presents will stop coming :) But I love that innocent part of the season. Do you really want that to end?
