Rescue remedy and arnica drops are what I used. Take plenty of powerade/lucoade. And yes lots of Nanna knickers. Jellybeans or barley sugars.The pads at NSH werent too bad and saved using mine and I had packed heaps of other stuff that I didnt really use. Did take my own nappies and nappy liners (to use as wipes much gentler on a newborn bum) and plenty of jumpsuits/onesies as they do poop alot.
As for clothing I did use my sarong and a t-shirt but I loved the shower and the birthing pool that when I was in there i was in my birthday suit. I only got dressed cause my contractions stopped so had to have syntocin & epi....food was crap at NSH some was ok but the food at the birthcentre was sooooo devine i so cant wait to go back there again in dec LOL
