Hi J.! Well I breastfeed my daughter until she was 6 months, but I fell into the same problem you are. She would take it at the first couple of times at like 2 wks old, but then I didn't have my husband try for awhile again. Then she wouldn't take it for NOTHING. Scream and didn't want anything to do with it. Even if I tried to give it to her, she pushed it away and tried going for my breast. But I stayed with the same bottle that was closes to her nuk of choice and they say to only do the bottle luke warm. Well our milk is body temp., so the milk is not as warm as what they would get from our breast if you do it just luke warm. (My sister in law helped with this one, from her doctor.) She told me to warm it up alittle more to warm, not where it is going to burn her but just a little warmer then you are now. Then have your husband give it to her. Worked like a charm, my daughter finally start taking the breast milk from the bottle agin. And I could go grocey shopping again without my husband calling saying you have to come home, she is hungery and screaming. I always warmed my bottle under the faucet, you can control the heat the best I think. But it is the temp. of the bottle and you even might try giving him something that has your scent on to feed her with. Like sleep with a blanket or that, so she smells you as he is feeding her. Just a thought to try and help too. Hope it works for you too, it worked right away for me. So not just luke warm, warm and hopefully she will drink it down like nothing. She is use too your milk temp. now. She knows what she likes.....
