One of the greenest things you can do is buy less stuff. Of course, that's easier said then done when the Incredible Growing Kid gets too big not only for his britches, but also for his bed. So instead of cribs, play tables, and storage that need to be replaced, we're featuring pieces that grow with your child--as well as design tips for repurposing old stuff and tricks for decorating to accommodate evolving interests. Whether you're setting up a nursery or a pretween's room, this approach is easy on the earth--and, in happy coincidence, on your wallet too.
