K.E.
I haven't experienced this personally, but you could try pumping on your right side to even yourself out. I don't know if you use bottles or pump at all, but maybe she would eat from the other side if dad was giving her a bottle. It's important that they eat from both sides not only for your health and comfort, but for baby's vision development and head growth. Pumping from the nonfavorite side and then having someone else feed her on their right might work.
