Baby items that you actually need?

Chelsea • My sweet hubby and I have been together since 2009. Our sweet Madilyn Ann born 11/5/16! We`re finally complete!
What are baby items that you actually need (big and small) and items you thought you needed but actually didn't? Trying to figure out what I need to buy. So far I have her crib, nursery swivel/glider chair, and car seat/stroller combo. On my to get list I have bassinet (for our room), baby swing, pack n play, dresser/changing table, ergo baby carrier, and some smaller essential items. What are items you actually used..? And items you thought you needed but ended up not using? 
Thanks mamas! 😘
