Breastfeeding problem

Rachel
My lo is 8wks old. I'm ftm. We are ebf. He has never had a bottle. Up until last Thursday we had never had a problem he would eat like a champ.. starting Thursday he would eat for like 3 min then pull off crying and nothing I would do would help. In the beginning of the problem it was just the right boob and only like one or two feedings a day. Today was the worst it had been every feeding since 1am and it didn't matter which boob. he is hungry but won't eat. But he is sleeping fine and is still having enough wet diapers so I don't know if anything is wrong or not. But my bobs hurt bc he isn't eating. And I feel so bad bc feeding time makes him cry so hard. Any advice would be appreciated.
