I'd plan on more receiving blankets. Mine always poo all over them right afterwards....
And, diapers? wipes? hats? nursing pads? I make a pile of stuff that prevents me from having to go farther than the bed to the bathroom for a while. So, more than one change of clothes for me and baby, lots of diapers, lansinoh, snacks, water bottles, something besides baby to keep me occupied, etc.
Extra towels for showering afterwards (i always do that so soon. My last 2 have been born with me upright, in the bathroom. Right after the placenta i'm all, "here...take the baby, let me get cleaned up", and then I dive into bed...the midwives are always shaking their heads in wonder at me, lol.)
A heating pad is nice for those first blankets, hats, clothes for the baby. You just pack them in a pillowcase all together and they are nicely warmed.
laundry basket (for the immediate stuff), and another for the stuff that you use in those first few days.
phone, phone numbers, camera (hate to be running around looking for that stuff)
baby carrier? belly band? granted, it may be 24-48 hours (or more) before you want either of those, but, again, i hate trying to find things, or worse, trying to tell someone else where it is.
yeah, and chux pads...love 'em, hate 'em. I'd consider a few more of those, too. Maybe you'll need them, maybe you won't, but there are some things I'd just rather throw away.
plastic coverings for the floor? again, i don't birth in bed, so we need something to protect carpet! even with, and being careful, dh had to clean up some blood drops after our last.
