Christmas Decorations

Livy is learning what "no" means.  It's taking her a long time to understand the concept and at times, she chooses not to listen.  I'm worried about putting up a Christmas Tree.  I can see it now, she will walk up to it with her walker and yank it down.  I can't imagine seeing a tree crushing my daughter.  I didn't decorate at all last year due to this fear, but I felt like it wasn't Christmas.  It's tradition to decorate.  I think I will wait until next weekend to put it all up so there's less time that it's up.  I guess my patience will be tested in the next month.
