I know some people will put baby gates around their trees or put ornaments up higher, but we've never had to do that. Our cats cause more problems than the kids! LO2 isn't mobile enough to get to the tree yet so maybe next year she will cause trouble. I guess I do tend to put the sentimental ornaments towards the top and the kid friendly ones at the bottom and let LO rearrange those ones.

Do you baby proof your Christmas tree? Or does your LO leave it alone for the most part?
