An organized closet is my DREAM COME TRUE. With a nursery I love that you can take advantage of the time you have to plan it. Is there any other room in the house where you get to plan the storage of items BEFORE you actually acquire the items.
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!
