For the baby: I packed a couple outfit options, just because we aren't sure of his size. There are 2 going home outfits (long footed onesies), a footed pant with a kimono top, hats, and a fleece footed onesie (it'll be the first week of march and I don't anticipate it being very warm). For the purposes of grooming, we packed baby nail cutters and more importantly a nail file, baby wipes, hand sanitizer, and Vaseline (I hear slathering this on helps with cleaning up the meconium aka first tar like poops). I also packed extra diapers and a swaddle blanket, I know the hospital provides plenty of their own, but just in case I waned to give it a go. And I also added extra card stock for baby foot prints, since it was easier than hauling his baby book along, and a thick receiving blanket that we ordered from Ava-Elliot (which I love).
For me: I packed 2 pairs of PJs, one's a long sleeved button down for easy feeding and skin-to-skin contact, and a going home outfit: yoga pants with a fold over waist, and a long tunic top. I went to target and picked up a few nursing tanks, so at least my middle will be covered, and some glorious granny panties. I know the hospital provides you with mesh undies, but I'm not sure if I'll like those. Grooming: I plan on showering so I can feel human again, so that requires the usual toiletries: shampoo, conditioner, shower gel, and of course a hair dryer, flat iron, and hairspray. Overnight essentials: face wipes, face wash, face lotion, deodorant, contacts, contact solution, glasses, and hair ties. A make up bag with just the basics: BB cream, eyeliner, and concealer. I also packed a pair of flip flops, and 2 pairs of comfy/warm socks. And because I'm not that into ice chips, I packed some hard candy: Lemonheads and Jolly Ranchers, and granola bars. Lastly, the postpartum care goodies: nipple cream, overnight pads aka thunder pads, Tucks medicated pads, Earth Mama Angel Baby Bottom Spray, a set of disposable breast pads (in case my milk comes in early), and Tylenol.
Tech bag (which is also packed in the Mister's bag): iPad, Kindle Fire, laptop (to send out the birth email to immediate friends and family), cameras (DSLR and the point and shoot), phones, and chargers for all electronics.
Other important stuff: ID & insurance cards, copy of my medical record file, cord blood paperwork/kit, and our pediatrician's contact information.
