I am very OCD about my tree. Last year, after about 15 years of a maroon and gold Christmas theme with ribbons, angels, and beautiful formal ornaments, I decided I was tired of it and wanted something more fun since I have a 6 year old boy. Last year I re-did my tree and mantle and absolutely love it. It's red, green, and white with candy and presents. It's so fun, a bit gaudy, but much more kid friendly and reflects more of who I am now. I let Caleb help me decorate the tree, but I did spread his ornaments around a bit. He also has a tree in his room that's more boyish and he can put anything he wants on that tree.
Here's a pic of my tree, (before I had the tree skirt around it)-it's a phone pic, so it's not that great, but you get the idea, and a pic of the mantle.
