If you want pack a couple of days worth of clothing that's comfortable for you or a robe so you're not having to wear hospital clothing, slippers are also good, or socks so you're not walking around the cold floor, underwear that you don't mind ruining, and pretty loose, pads that are long and thick that will be comfortable for you (hospital ones SUCK), if you plan on nursing, nursing bras/tank top, nursing pillow, breast pads, cream, charger, makeup/hair stuff (you'll be getting pictures taken left and right..trust me I regret this not having them last time hahah), travel pack shampoo, conditioner, deoderant, tooth paste, tooth brush, soap, hair tyes (hospitals carry these sometimes, but my last actually only left body wash so I had to use it in my hair for 3 days..yuck!) fiber snacks (usually you have to have your first BM in the hospital and it friggen hurts pushing, this makes it easier), medicine if you take any, I'd continue prenatals so you don't get drained right after, especially breast feeding, your own pillow if you're particular, and camera and extra batteries. That's my list so far.. probably will end up adding to it!

I would say between 2-3 sleepers & onsies. Some hats and mitts. Blanket or two. A carseat cover. A couple diapers and some wipes. An outfit to take the baby home in. Soother if u are going to use one. I think that is all I put in the baby's bag this time. I tried not to over pack this time.
Good luck :-)
