He knows what I've told him, but I don't think he truly grasps the whole concept.
He knows we have gifts to give our family members b/c of the gifts that are currently under our tree. I told him Santa only brings gifts to good girls & boys.
He ripped the chimney off his new Caillou tree house & he said - "Santa come down the chimney!" LOL (We've been watching the Grinch & Twas the Night Before Christmas, so he's seen Santa come down the chimney)
I guess I'll have to wait till Tuesday to see how much he actually "gets" Christmas.
