I am always surprised by the fact that my dck's are respectful of my tree. Sure, I will see a little hand reach out to touch an ornament, so I will just say "look with your eyes only please" and they do.
when I was 4 I knocked over our Christmas tree twice in one hour. Just curious, and of course that is what happens when pregnant Mom has a nap leaving me to my own devises. Ah, the good old days eh? Haha
