I have had three C-sections,the last one being in HK at the Adventist.I never had any problems BF other than the normal "newbie" issues first time around.Nothing that a good lactation consultant or nurse couldn't assist me with.
With my first two I had the baby with me from delivery to being wheeled into my room and baby latched on with in half and hour of delivery.My third,here in HK,they wanted to"warm" the baby first.I told them to bring the baby to me immediately and insisted that there was nothing warmer for him than being next to me.They relented and I had my baby room in with me as much as I wanted even though I was not in a private ward.As a third time mother I felt more confident and ready to stand my ground.I did feel that if I was a first time mom delivering there it might not have been so supportive.
Having said that,I was under the impression that they would try and schedule my baby when he was in the nursery and only bring him to me say every three to four hours.This was not the case and never once was he crying when the bought him to me which tells me they were watching for all the other clues that baby was hungry before the crying.
To sum up,physically I had no issues with breastfeeding after a C-section.I was very sure in my decision to make a success of it no matter what and to do it exclusively,I think this can make all the difference.
I had much more support with my first two deliveries than with my third at the Adventist,but maybe thats just because they figured I did not need as much help.
Attend some La Leche meeting before the birth and have a couple of numbers handy so that you can call on outside assistance if you need it.
PS Off the BF topic but something I had in my last to sections which I thought was just wonderful.The surgical screen was lowered for me to see my baby being lifted out into the world-as close to "natural childbirth" as you can get in an operating theatre!!I highly recommend it
