Any "Must Need" Suggestions?

What are the "Must Need(s)" you suggest to get before the baby comes? I'm not due until September, so I still have time, and I also won't have my baby shower until July,  but is there anything you'd recommend to imminently get or convenient to have before the arrival of the baby . (Besides the obvious like diapers/wipes, clothes ect ect)
