Mommies help!

My 6 month old has been breastfeed only since 2 months. I’ve tried every single bottle there is and nothing works. He will drink water from any bottle but not my breast milk. I’ve tired to feed h bottle but as soon as he tastes milk he get mad and starts crying. His doctor says I can’t be in the room so my husband tries (well I wouldn’t even call it that) he gives up and doesn’t try till weeks later. He’s moved on to solids so that helps a little and I’m terrified to see what happens when his teeth start coming in. Do y’all have any tips?
