The more I think of it, the more I'm loving the idea of a floor bed (or, montessori-style bed) for Cheech once we get her into her own room. The reason we don't have our bed on the floor now is because when you live and run a business out of a 650 sq. ft. space with a baby, you use every single nook and cranny possible for storage. Cheech isn't walking yet, and THANKFULLY hasn't been showing extreme amounts of interest, but I imagine once she does figure it out, having her sleep in our bed when we're not in it might be a tad bit scary.
Anyway, I just wanted to thank all of you who suggested it. It really is the most practical solution, and I have no idea why it never crossed my mind.
Also, TONS of thanks for all your thoughts regarding sharing. It's fascinating and educational to learn all the approaches different parents choose to take and why.
