Two month old upset when try to feed

Nicole • Married to my soulmate. In love with our perfect daughter Addison (03/20/19) 💖

So normally my two month old daughter is a very good eater. For some reason today I’ve only been able to feed her twice- at 7:30am and 12:30pm. She gets so upset when I try to put my breast in her mouth. But is all about the pacifier and basically just keeps going to sleep. Is she just super tired today?? She always sleeps well at night but maybe last night she didn’t?
