Kristine,
I ran your question past my friend who is a chiropractor, mom of three and natural childbirth educator like myself -- and this was her idea:
"Could be that it's his TMJ [temperomandibular joint dysfunction]. I've seen MANY babies with jaws misaligned, less than a true dislocation where nursing is difficult and less effective than just taking it from a bottle. Especially with a C-section or any delivery where the OB uses the head as a handle, there frequently can be jaw issues. Not that the bottle at birth helped the situation. What does LLL call that? Nipple preference...rather than what they use to call it - nipple confusion. It's not a phase - there IS something wrong - moms know."
So, trust your instincts. It's likley NOT a "phase" or that there is anything about your breast or milk that is putting him off -- it is more likely an imbalance in his jaw that can be easily corrected (TMJ rebalancing or an actual adjustment) by a chiropractor who specializes in this. After getting that taken care of (and possibly even before), I would also recommend you slow down on giving him the bottle as a concession to his objections (but keep pumping until you can sort this out) and let him get hungrier and let him know the breast is how he's going to get his food. The docs and nurses have set you up for failure by introducing a bottle at birth (which, by the way, was totally unnecessary even with his blood sugar issues, which is a whole other story....), but that doesn't mean you have to give in to this. You CAN turn it around with persistence and getting the right help. Going to a chiropractor would be the very first thing I'd try.
