I'm glad you are being monitored and have some time to prepare for this, i wish you all the very best.
We had a similar problem ,identified at 27 weeks, i went into hospital and had a doppler every other day for a week.
my son was delivered at 28weeks +3 weighing 1pound 11. I tried very hard to express milk using the electrical pumps available in the SCU and we also hired one to use at home, but the milk never really came in any great amount.
But most of the other mums in the unit had more than they needed at the time, so were freezing dozens of bottles to be used later when their baby needed more. I just told myself any of mother's milk (MM they called it) was better than none.
I continued to try to express for the 3 months he was in hospital as he was never really able to latch on, and was too weak to suck, however when he came home, our amazing midwife was able to latch him on in less than 2 weeks. If only this help was given in the unit earlier we might have been successful and been able to establish a flow. I gave up after 5 months, and regret not being able to bf for longer, but many other mothers in the unit did not have this problem.
Having a c-section never really bothered me, they are common and i knew he had to come out as he wasn't able to survive any longer inside. You have lots of time to bond with him later, doing 'kangaroo care' holding him against your skin and letting him smell you, feel your heart beat, breathing, listen to your voice etc.
The environment of a SCU unit is obviously difficult and we visited before to have a look around and try to understand the equipment, tubes, lines etc, so try to visit if possible. maybe take a pen and paper to note down the details given of the special care provided and equipment used. My husband was able to take in some of the details, but i found it hard at the begining to remember what machine did what and what all the measurements displayed on the monitors meant.
For very premature babies their heart rate, pulse, level of oxygen in the blood, blood pressure is constantly monitored and its helpful to understand what all the numbers mean.
I also bought 2 books, 'the premature baby book' and 'your premature baby and child' to refer to, they are helpful/reassurung and scary at first.
my son is now one and a half and doing very well.
best of luck
