Here is a list of things that you will need at least to start.
furniture
crib
mattress
dresser(s)
bassinet and pad(mattress)
some people will say that you need a changing table but I don't really think it's necessary. I have one that i've used a total of three times. I usually change the baby on the couch, bed or floor. I do recommend a couple changing pads (they sell them for a dollar in walmart).
feeding
bibs
pacifier (about 5 or 6 because they disappear)
bottle brushes
bottle warmer
bottles
nipples (get a lot they wear out or disappear in the sink

)
bottle caps
if breastfeeding then get a good pump and nursing pads. I also recommend storage containers for freezing or refrigerating your milk.
bathing
baby bath tup
hooded bath towels (4 or 5)
wash cloths (i recommend getting a lot of these)
nail scissors
nail clippers
brush & comb
bath soap (mild)
lotion
baby oil
vaseline
clothing & changing supplies
diapers
onesies (get a lot then you don't have to do laundry as often)
one pieces outfits
sleepers
interchangeable separates
socks
crib shoes
receiving blankets (we still use these)
side snap undershirts
miscellaneous
stroller
toys
bouncer seat (this saved my life!)
photo album
thermometer
aspirator
crib sheets (at least 4 sets)
bumper pad
ummm... That's all I can think of right now....
