You can easily get baby clothes second hand, we had lovely ones, DD being baby no. 4 in them, soft, cosy and they outgrow them fast. Hardly a point in buying new. Ours went to baby no. 5 and I think after that finally in the rags bin. Otherwise supermarkets and H&M do nice clothes for not a lot of money.
We also had a crib and moses basket second hand. I preferred having something downstairs for naps and our bedroom had no room for a cot.
We got formular and bottles but I found that after 6 months I was glad to move from bf to bottles so they just took up space. They were really simple ones, no need for singing and dancing ones unless you know you need them.
Dummies were pointless, DD actually managed to spit them across the room.
Muslin squares by the bucket load. They do double as emergency bibs when older, thin blankets on hot days or just to mop off spills. My cleaner now uses them (DD is 12 years old).
Get some washable wipes for home (if you are handy with sewing or know someone just get thin terry cloth and cut in size) and just keep normal ones in a changing bags, better for the envrionment anyway and save money on the long run. Ours went in the wash together with the washable nappies. You need a bin with a decent lid for the nappies, I just put them in the bin, closed the lid and washed every second day.
Even if you want to use a sling I found a pram handy. Not only did DD object to a sling when she was a bit older the pram is handy to store all kind of stuff when you are out.
We bought Weleda baby wash/nappy cream as I found most big brands are full of chemicals. You actually don't need nappy cream as a general thing, we only did it when DD was a bit sore during poonamies. Even with washable nappies normal cleaning is enough. You also don't need to bath a baby every day, that comes when you start weaning.
We had disposable nappies in hospital, easier to deal with and DD was also so skinny it took a month to get her to fit into them. Maybe get one pack as a back up.
