We put our tree up really early this year. The Saturday before Thanksgiving. I wasn't too bad, I didn't actually get sick of it as soon as I thought I would. We didn't decorate it until after Thanksgiving and I think that is what helped, keeping less clutter on it.
We borrowed a neighbors train set for a little over a week. They were going out of town and they offered for us to take it. Westin got some good use out of it for that week. Every night we got it our set it up and played for a while. He was also really good about putting it away each day.
