Ok so out of what I did take to the hospital I found that my nursing tank was a very wise investment. Once I put it on under my nursing gown it made nursing soo much easier and even easier to switch sides without exposing yourself for all to see. After a few days I switched to my clothing (my night gown, underwear and such). I would definitely wait until your bleeding is under control though and it is like a period for you instead of real heavy stuff.
Something I wish I would have thought of was those Wisp no water needed toothbrushes, facial cleansing wipes and a bottle of detangling spray. After so long of laboring and then having a c-section I felt like crap and wanted nothing more then to just do basic hygiene. I was able to brush out my hair, the nurse brought me a little pan of water that I used to get my hair unmatted and a washcloth that I wiped my face down with but I didn't feel clean. I especially didn't feel clean since right before my c-section started I was throwing up (not easy to do when you can't feel your muscles, laying on your back and your arms are strapped down on each side...)
Last but not least, I forgot my lotion. The hospital was TERRIBLY dry and I had labored twice in the tub. My skin was so dry and itchy that it drove me nuts!
I do recommend setting the TV on a channel that has shows that are easy to drift in and out of during labor. It was a great distraction during labor. I did the same thing at night since DH didn't stay at the hospital (no place for him to sleep comfortably) it helped me when I would wake up alone and gave enough light that when they bought in Elizabeth I could see her.
Well thats all, I thought I would share what worked for me at the hospital since it was my first baby.

good luck ladies and I hope you all have easy deliveries.
