See a professional breastfeeding consultant, most nurses/midwives in hospital aren't internationally certified and just offer their "advise" which is just as good as the advise from say an aunt or mother, get someone to assist you afterwards and at home, make freezer meals. Buy a carriwell support band! This will help you to be more mobile which then helps you heal faster.
You can't eat anything before so perhaps have something you can eat afterwards. Hold your baby as soon as possible and don't feel bad if you need her to sleep in the nursery for a couple of hours if you need the rest. My partner stayed with me until discharge. Don't get out of the bed unless you have to use the bathroom, and use it every two hours. Breastfeed baby in bed. Don't bother to shower, there's no shame in being washed by nurses, after all you did just have abdominal surgery! Get ready to be bothered by nurses/midwives/marketing/Doctors every say 30 - 45 minutes. It's not nice to have a c-section, it does hurt a lot, but if your baby is in jeopardy then all this is worth it.
