I work in an elementary school and don't really hear kids discussing Santa gifts, or any other gifts when they come back to school after Christmas, so I wouldn't worry about that. I think parents think about this a lot more than kids do! I've always told dd that she can make a list for Santa, but she gets what he wants her to have, which may or may not be on her list. I suppose that way, if she ever did try to compare with someone else's, I can say that what she got was what Santa personally chose for her to have and that makes it special no matter what anyone else got. I don't expect that to ever come up though; I don't recall ever talking about what I got for Christmas once I got back to school.
