Use a curtain and a stool to create a bedside-table with a hidden locker. We needed a small bedside table for our guestroom. Using an Oddvar stool and Ingmaj curtain and two drawer slides, we created a bedside locker with a sliding top board.
Under-crib storage Utilize under-crib space with big storage boxes for extra diapers, wipes, and more. Keep the storage box out of sight with a crib skirt. Already use that space for storage, but putting a container would make it a lot easier to clean!
Shelves mounted on wall above dresser/changing table? Would need to fold pre-folds in half to make the shelves not need to be too deep. Would be easy to keep everything in arm's reach and not interfere with the "reading nook".
