Congrats, eenii! Is this your first? Our 8th baby is due the end of October. You got a great deal on that pump!
Yikes OBO, please tell me you're joking. That list sounds like an ad from one of those parenting magazines.
Babies truly don't need much. It is nice to have some disposable diapers/wipers for the first couple of weeks - those meconium diapers are pretty nasty. Even if you plan to use disposables all the time, it's good to have some cloth diapers and covers or pins/nylon pants in case you run out. You want about 4 dozen nice, thick cloth diapers and several sets of pins, plus covers or pants in each size up to toddler for preps. Cloth diapers are great for cleaning up messes, using for burp cloths and washing windows!
For wipers you can get some cheapo washclothes, but I usually use scrap flannel from Dh's old shirts or pieces leftover from when the girls try to sew. I just wash them right along with the diapers.
Clothes are variable. I like onsies and sleepers when they are little, then sweats and t-shirts are great. (I really hate the nightgowns and never, ever use 'em.) Socks of course. A couple sets of booties if you live where it gets cold (I don't think I've ever used more than 2 sets of booties on any baby!). For preps you might want to hit yard sales for clothing up to toddler sizes. Go way easy on any one size (especially newborn!), they outgrow them VERY quickly. They don't need shoes at all until they learn to walk, and there's no telling what size their feet will be at that point.
Get 2 or 3 nice heavy blankets if you live in a cold climate, as well as a few receiving blankets. You'll also want 2 hats when they're tiny if you are in a cold climate.
Babies don't need baby food, they can eat mushed up table food. You can get a hand-powered baby food grinder if you really want one, or look for baby food recipes online or in a baby food cookbook. But they usually catch on to table food remarkably quickly.
Vitamins, Tylenol, a couple of thermometers and some tiny nail clippers would all be good. A couple of little toothbrushes for when he/she starts getting teeth would be nice.
A sling or some sort of carrier is great. Those little ones get HEAVY when you've been hauling 'em around for a while! A good, sturdy diaper bag or backpack is worth its weight in gold.
Thinking, thinking....hmm...that's probably about it. You don't even really need a crib or a highchair or any of those other things that we tend to think of as "necessary." They're nice to have to be sure, but not NECESSARY.
Don't worry, you'll figure it out right quick.
