We have a 14 month old DD who loves to get into things, but we've actually had 2 christmas trees up for a few weeks now. She was VERY excited when the tree was going up and wanted to touch all the ornaments, etc. We let her point at them and touch them, but if she started to try to yank one down, we told her not to do that. Now, shes kindof used to them. She'll go look, and if someone new comes over, she'll go show them the tree, but its not as big of a deal anymore. I'd definitely put the tree up then just go from there. Good luck.
