Have some feed her while you’re gone.

Try kiinde it’s a whole breastfeeding system

Try different bottles and leave the room. Have someone else feed her.

Best of wishes. Mine never took one. We tried everything we could think of and more. Hope you have a better outcome. She didn't quit nursing until I force weaned her in January at 20 months. And now she still throws fits trying to get me to let her nurse. She started drinking from a straw at 5 months though so maybe you can try that?
