Why do you have to have a year without Santa?
My kids are 26 and 17 and they have yet to not having something under the tree from Santa.
My daughter, the 26 year old would make wish lists a mile long. She was never afraid to ask for anything. As for asking for a horse, trust me, she did. I said a horse would be lovely, but then Santa would have to buy us a whole new house because we had nowhere to put a horse. It kind of helped her see how silly the idea was. That WAS asking a bit much considering all the millions of kids in the world. :)
My son, the 17 year old, he was always happy with anything. He just wasn't one for saying that he wanted things. He worried more about getting things for other people. He's still that way.
From the time my kids were little, we went through their clothes and toys and donated things they'd outgrown to the local rescue mission. We donated nice things, not things that were worn out or stained. Also, we went to the store and bought everything necessary for a Christmas dinner and donated that to the mission as well. There are so many homeless families and little kids without a decent coat or rainboots. It was pretty easy to get my kids to think of things beyond what they would get.
I think your daughter should go to bed at her regular bedtime. My son is 17 and he goes to bed fairly early on Christmas Eve. He knows not to come out of his room or mess with my mojo. My ex husband can never wait to give him his presents, so Christmas morning is all Mom and Santa. And I love everything about it.
Your daughter is only 11. Just because you told her there really isn't a Santa, I don't see why she has to miss out on the fun or surprise of Christmas morning. Why stay up with the adults? She's far from being an adult herself. I mean, why even wrap presents at all? I fear this could be the year that Christmas comes to a screeching halt as she knew it. She's too young for that to happen. There's no reason to completely lose the magic of Christmas.
Just my opinion.
