Her closet has a top shelf that is hard to get to so I bought two large bins and I store our back up inventory of diapers and extra blankets in them.
Her dirty clothes hamper matches the bins and sits on the floor under the 'long hang' rod since her clothes are so tiny and we have a lot of space there. I also have a smaller hamper for her downstairs so I don't have to treck up to her room every time she soils something. Another perk about her short, tiny clothes, is the extra space under her double rods. I keep her pack and play and suitcase on the floor there.
I registered for baby hangers and ended up hanging a lot of her clothes. I bought these cool hanging dividers to keep her clothes sectioned off by age/size. This has been extremely helpful because I know exactly where I can pull from for her size at the moment.
Over the door I hung a trio of hooks that hold her little tote bags and over night duffles.
