Sleep help!!!!!!!!!!!

Am

My four month old went from sleeping 10:30pm-6am to waking every hour 😱 I am in hell. She is ebf and has cluster fed all weekend. I feel like the last 2 days she has sucked me completely dry and she is SO fussy when nursing. She will not take a bottle, or a binkie and only wants me and my boobs but cries when she starts to suckle. I’ve gotten no sleep at all and have to go back to work tomorrow 😭 I’m wondering if she may possibly have an ear infection just because she is SO fussy when nursing and this is all sudden? She went 2-3 days not eating well so I was engorged prior to this and then cluster feeding all day and night. Gah. I remember a regression with my son but he never slept through the night ever until he was like 15 months old so it wasn’t as bad as this has been. My son also never ever ever has any other symptoms with ear infections. I took him once to get checked for pink eye and they were like and he’s got a double ear infection I was like wtf??? How?? 😂
