We too have a small fake tree that only went up yesterday. It was supposed to go up the day of the church play but we were too busy.
I buy presents because I want too but at least half the presents are clothes bought on sale. They have a big Lego set to share and a smaller educational toy each that they will share after the first week. The only non sharing toys in our house are teddies/dolls and things less than a week old. I come from a background where things are automatically passed down so the idea of permanent ownership doesn't exist for me. I would have loved to get them new scooters and a cheap tablet but finances didn't stretch to that this year.
