My walmart doesn't carry them, I ordered them online and they came pretty quickly--I ordered a bunch and returned the ones I didn't like as well

If worst comes to worst and you need a nursing cami and can't find one to buy...you could get a regular tank and turn it into a nursing one! Even if you can't sew it isn't to hard to do.  If you have a nursing bra you hook the loop onto the bra hook if not I used snaps (or button to hook over the loop you made).  I have seen some tutorials on Pinterest also...might be worth checking out!  If you don't sew at all...do you know anyone that does?  It really is super easy to do yourself though!  Good Luck!  :)

My preference for nursing in the hospital was nursing cami's target sells them, but I got mine online at walmart for cheaper.  They are more comfortable to sleep in and only your breast is exposed when nursing it keeps your belly covered which I liked when everyone and his brother walks into your hospital room.

I also brought my own pj's--well maternity tops and pj pants/yoga pants.  I had a c-section and was in the hospital for 5 days--i stayed in the hospital gown the day of delivery but as soon as could shower wore my own clothes.  I did wear the hospital undies that you just throw out.  You also will probably want slippers or flip flops.  And tolietries. 

I also was glad I had packed a special blanket--when the photographer came in we used it for a lot of the pictures.
