This is such a good thread!!
Definitely echo everything the ladies have said before hand - stay calm, listen to your body and your midwife - you CAN do this, our body is designed for it!
Sleep when you can, eat if you want to - I didn't want anything.. stay hydrated.
Don't panic if you throw up - I did at the transitional stage, but was fine after that.
Bring socks... my feet got really cold for some reason ???
Heaps of knickers... but make sure they're comfy and relatively "snug" to hold pads in place securely. I used two pads at a time as I really didn't want any leakages!
Dark PJ bottoms are a good idea too, just makes you a little bit less paranoid about leaks.
I also lay on one of those disposable nappy change pads that they have in hospitals - I didn't leak but at least if I did it's easier to change one of those than ask the nurse to change the sheets!
Bring snacks.... hospital food is usually not very appetizing. Have family bring in cooked meals if they allow it in your hospital. Have some fruit at hand, sorry if this is TMI but you really want that first bowel movement to be as soft as possible!!!!
Don't spend all your time lying on the bed - they're hard and not comfy at all for the bottom region after all it's been through!! Bring a comfy cushion / pillow from home, pop it on a nice supportive chair and sit there as much as possible!
