I have a son who is 13 months old we had a few must haves that were different from the above poster.
-diaper genie or similar product if you are using disposable diapers, it cuts down on smell in the changing area.
-my son loved to be swaddled and recieving blankets just were not big enough for him and he was swaddled most of the time for several months. It was the only way he would sleep. This is the type we found worked best for us.

-My son hated the swing, but loved to jump so the jumperoo from fisher price was a life saver.

-bouncy seat wonderful way for him to sit, play and just be when you dont want to hold him
-pack n' play- good for a temp crib when he is smaller my son slept in it in our room until we moved him to his own. We now use it for travel and when he was younger for outside play.
-when he was really little and still trying tummy time and that sort of thing a foldable activity gym with mat was nice. The crossing bars can usually have toys clipped to them that you can change out so baby wont get bored.

-I personally wished I had waited to get a breast pump until I knew what type I would need after the baby. I got a hand pump before and I needed a stronger one so ended up paying for a strong one later on, but the pump was a must have.
-there is the usuall clothes, blankets, towells ect.
-i had the bijorn but a hip carrier or sling makes more sence to me now as my son was too heavy for the bijorn by about 5 months.
-infant tylenol, myconex (sp?), diaper rash cream, size one and 2 diapers (my son grew out of size ones quickly and was never in newborn. baby wash
finally something for winter I used a fleece infant snowsuit for my son so we could walk outside but there is also a fleece blanket designed to fit around the car seat. Those work well if they are still in the infant size seat.
