Oh gosh this brings back memories! Don't know if I can be much help as we never really got there in the end, maybe my experience can help with what not to do? lol
DD was born at 28 weeks (an October bub too smile ) and it was almost 4 months before she was strong enough to breastfeed (and even then we had trouble). We used a "haberman" bottle (medela make them), which are much easier to drink from and are designed to reduce "bottle suck" as well as allowing bub to regulate their own milk flow. In the beginning she'd tire quickly in the beginning and the nurses would tube-feed her anything she didn't drink but slowly she'd take more and more. We did a system of breastfeed, then ebm, then tube feed (depending on how much she'd taken)
I never managed to get her to breastfeed fully and (as you can imagine) essentially feeding 3 times at every feed, plus expressing and all that goes with it (particularly once she was home and I was doing it all on my own) drove me crazy!
Much of the problem I think was that she just had no idea what the bottle / breast is for. They lack the rooting reflex and feeding instinct of a term bub so when they get upset because they're hungry, they don't make the connection between that and the milk you're offering. All I can say here is hang in there, they do work it out eventually.
I guess my advice would be to prepare for hurdles, but be positive too. I've successfully bf 2 babies since then and looking back, I think I was so focused on breastFEEDING that it became a stressful time for both of us. I think lots of time at the breast (whether she is feeding or not) gives her time to learn to suck without pressure and to just enjoy the closeness and skin contact. If she's latching well then even a 2 min "feed" is a positive step forward. Ask the nurses if there's somewhere you can go, even if it's an unused meeting room just to allow her that time.
HTH and good luck!
