New born essentials

What would you guys say are some new born essentials? I have a whole bottle set, with a bottle brush and different size nipples as well, bottle warmer and sterilizer, pack and play with a attachable bassinet, car seat and stroller, baby bath, a bunch of clothes going until 6 months so far. Any suggestions what else is NEEDED? I have my crib, and nursery set for the crib on my registry. I know somethings are nice to have but what is necessary? What can you mommas not do with without? ( my pack and play if I don’t use as a crib, can also be used for a changing station ) I’m asking because financially we can’t afford much, we are already struggling as is so I’m just looking for the most necessary items
