You should be very proud of yourself. Have you thought of painting it in bright colors? I did on mine and it looks sooooo kid friendly and cute. Just an idea. Those are also beautiful children.
I've been checking out coops to upgrade my 4 girls that I could set directly on granite ground. Ur's looks like it would work great. I kinda like the rustic look of urs. It would be hard for me to decide whether to keep that look and just give it a coat of polyurethane or paint it in cute colors. With the kids I would probably paint it.
