Ha, we are in the same situation to the T. We just put our tree up this evening and we left off the two bottom rows of branches. Then we didn't put any ornaments any lower than where she could reach. Needless to say we don't have near as many ornaments on so it took no time to put it up. We do use the kid friendly ornament hangers and not those metal ones.
We thought about the table idea, but I didn't feel like we had a sturdy enough table. She will pull up on anything and everything, and the last thing I want is for her to pull up knock over the table and tree on to herself. I would have done the table idea if I felt like we had one sturdy enough, and small enough not to take over our living room.
I will not be putting any gifts under the tree until two seconds before we open them. I'll just lay them on our guest bed so my son can still see them and guess what's inside.
I'm sure no mater what I do and how much I try to prevent it she will find herself in the tree sometime between now and when it's gone. It's not like she will be the first child to ever find herself in the tree. What did our parents do before baby gates, and when most trees where real trees. Good luck and Merry Christmas.
