We put the tree up as normal, and just persevered with telling Abbie "no" and taking her away from it if she tried to play/dismantle it. Our method has always been leave everything as it is (so we didn't move ornaments etc off lower tables) and teach her not to touch, rather than changing everything and her never having to learn that some things aren't for her to play with.Not saying that's the right thing to do - it's just our way!
