Z is over the moon with excitement for her updated, less "babyish" room. She'd still like a bigger (read double or bunk) bed, but that's not going to happen. What I do still want to find is a mirror for the wall between her wardrobe and the door and new knobs for her wardrobe. In the meantime, we're both thrilled with the new rug, wall decals and throw pillows.
Making these changes in Z's room did have one unintended consequence: the first serious bout of sibling rivalry on A's part. She desperately wants to have a "big bed, new sheets and a rug... like Z." We're working on it.
