Hi - baby fed fine this morning but later, during a bit of a crying fit, she point-blank refused the breast when usually she would latch on for the comfort. This has carried on throughout the day - right now she's screaming her head off and wouldn't latch on when I tried to feed her earlier. We have EBM but I'm terrified this is going to keep going... I have no idea what to do. She doesn't seem unwell - just won't stop screaming.
