Hello - you need all the obvious stuff, nighties (breastfeeding), nice dressing gown in case you need to stay. Toiletries. You need to get panty pads, I was told not the ones with sticky on them as if you have stitches - then well, you can use your imagination!!! Mothercare do good thick ones with no sticky!! I used alot of these.
Muslins, something for the baby to wear. Nappies, wipes or cotton wool, whichever you're going to use. Oh and breastpads!
I took those clean your face wipes things, which are good if you're feeling a bit scuzzy at any point. I also took lollies for the labour, which again was recommended. My hospital wouldn't let me eat but when my blood sugar dropped at one point the midwife did let me have a lolly and it was very nice!!
oh - and you might like something to listen to - ipod or whatever.
I wouldn't go too mad, you can send whoever out to get things if you get stuck and I know people who had lovely normal births (not like my disaster) who popped into the shops on the way home!
I think Mothercare do a list on their website...
