breast to whole struggles

Has anyone struggled to transition their LO from breast to whole milk? I EBF and now thar she is 1, I have been trying to transition her but she has absolutely no interest in whole milk. i tried to put a little whole milk in her bottle of breast milk and she wanted nothing to do with it. She has always preferred the breast over everything and refused all, and I mean all, differwnt types of formula when she was younger. My supply has always been low but enough for her. She nurses before I leave the house in the morning and at night but no milk in between. I would love for her to take tge whole milk since I'm down to 2 ounces when I pump. We need help!
