after pains when breastfeeding can really hurt
if you don't instsntly bond with your baby don't worry, some people don't but it comes, just don't listen to all the 'other' mums saying they do and feel really crap that you didn't - you are normal
you can bleed lots - buy twice as many maternity pads as you think you'll need
take your OH to mothercare and boots, show him exactly what you might need, ie if you don't buy formula and bottles beforehand say which ones you would like to use in case he needs to get them in a hurry/unexpectedly - same for maternity pads, nipple cream, infacol etc it makes his shopping trip much quicker!
trust your instincts - you are right more times than you are wrong
lower your housework standards (as has been said )
after a hard day go and look at them sleeping just to remind yourself why they are worth it
listen to advice, take the bits you like, ignore what you don't
I'll probably think of some more this is my first draft hope everything goes really well for your Bro and SIL
