Despite my initial reservations between kid and cat damage, we put up a Christmas tree. I tried to be "smart" about it, so it only has unbreakable lights, garland and ornaments. So, when it goes down, and it almost surely will, nothing will shatter! Hollis is really pleased with it: she can't wait to go and sit by it and play with her toys, and to sneak a pull on the lights when we're not looking.
Here's Hollis looking at the tree with awe, and a video of her playing with one of her old favorite toys, with some assistance from our cat Jasper.
