Give the ABA a call - they can give you specific advice on breastfeeding after a c/s and breastfeeding a prem (or baby in need of extra care).
You never know what this baby will be like, so just wait and see. A sling or carrier of some sort would be very useful if you're baby needs to be held a lot - that can leave you hands free to get other things done (and your baby may even be able to feed in there).

Do you feel more confident info/education-wise this time? Joining the ABA and even doing their breastfeeding education class or just attending some meetings could be really helpful. Maybe also think about who you can turn to for support - for breastfeeding-specific support, but also help at home (mum, MIL, friends...)

And we're always here of course.
