Frustrated

My almost 2 month old has been a champ at breastfeeding until now! The last couple of days she’ll only latch for about 2 minutes on each breast then just cry and cry after that. I try burping her, changing her diaper, hand expressing for her, changing positions and nothing will get her to latch again. As some background she does take a bottle with pumped milk when I’m at work (for various reasons I went back to work at 2 weeks so a bottle is not a new thing for her) and I haven’t changed anything in my diet. I can tell she’s stil hungry. Anyone have any ideas? What worked for you?
