Yes, you will likely be asked if you will donate your placenta so you might want to read up on this beforehand. I said no as I was taken by surprise just before surgery and hadn't had chance to read up on it. I just didn't like the thought of it being used for DNA research & development, for example.
Take lots and lots of easy snack food and drinks.
Take nightdresses (with button opening if poss for skin to skin/bf) not pyjama bottoms - firstly any waistband near the area doesn't feel good and secondly, you will find it awkward stepping into them post-caesarean.
Take BIG SOFT KNICKERS and plenty of them! Not paper knickers, they aren't that comfy. You want waist-high bloomers so the waistband is nowhere near the scar.
Take all the painkillers properly. If you do that, any pain is managed very successfully and you won't really be too aware of the cs.
Take plenty of easy reading. You might not be able to move for a while, but newborns often sleep a lot for the first day or two, so there will be times when the baby is asleep but you can't easily get up for wanders or to chat. You will be in for a minimum of 24 hours (some hospitals offer fast track discharge, where they take your constantly and if no probs you can leave after 24 hours). Other hospitals are a 48 hour discharge so there will be times with no visitors and baby asleep where you want something to do/read!
Please do follow the advice and don't think about hoovering, lifting anything or ironing etc any time soon after the CS. You can prolong your recovery if you try to take things too fast.
And finally, enjoy! I have had 3CSs (1 emergency, 2 planned) and all (even the emergency) were pretty good, minimal pain, good recovery, no problems breastfeeding from the start!
