I'm a huge believer that Christmas is the most wonderful time of the year and take my traditions very seriously :) I'd never even dream of not having a tree up! We have a baby AND a cat for the first time, so it will be an adventure.
Modifications: 1. Not putting up the vintage bulbs that belonged to my great grandmother. 2. Only large, non-breakable ornaments on the bottom. 3. Bottom and more fragile or heavy ornaments will be tied on. 4. No tinsel- this one makes me the saddest, but I know if any gets on the floor (which is inevitable) it will be in either DS's or the cat's mouth. Tinsel can kill a cat. I'm not sure what it does to people, but it can't be good. I might invest in a bunch of little icicles or something to add that extra sparkle. 5. Placing the tree in the corner to reduce the mass of temptation, and putting a barrier of toy boxes, blankets and large toys around the bottom.
We do have a fake tree, so in some cases I can just bend the branches back to secure the ornaments on.
