I know some of your kids have special needs, like my Christian.
I used to think he didn't care about Christmas too. He is very autistic and holidays are just not important to him (unless there is cake involved!) We joke that we save a lot of money on him at Christmas! But over the years I've changed my mind. I realize that he *does* show subtle signs of recognizing symbols of the Christmas season. At Thanksgiving, I witnessed him go over to the corner where we usually put up the tree. He stood there in the corner hugging himself and rubbing his arms--that's one of his signs of feeling happy; it's an extention of his "more" sign. So there he was, hugging and hugging. It finally dawned on me that he was trying to convey the thought that he wanted the Christmas tree to appear. Somehow I never made the connection until now. It was quite an epiphany for me and I ran quick and dug out the tree and the lights. He was in Hog Heaven!
I know I'm not telling you anything you don't know, but I feel like our kids learn in a lot of little and big ways. We never know what is going to be the *one* small thing that turns the key that unlocks a new thought, a new skill, of a new understanding. I try to remember that just because Christian can't tell me stuff, doesn't mean he doesn't feel, understand and remember stuff.
Merry Christmas to all your little (and big!) ones
