Back in the day i worked in an infant room at a center, I had a few babies throughout the years that refused a bottle because they were breastfed. Suggestion- try having them feed on a boppy pillow with an article of clothing from mom next to them. Try using a dr. Brown bottle. Another one would only feed in the baby carrier- faced away from me with canopy up. The only thing she could see/smell was my hand. Another one needed breast milk in a sippy cup and tip back and forth. It took forever but with patience she drank it. Not a sippy that had a stopper or needed to suck. And finally one mom would come every lunch break and come feed. Good luck. The stress of the adults doesn't help baby.
