Probably teething..?

So

My son has been waking up every 30 mins to nurse at night. Idk wtf is going on, I want to cry over how exhausted I am. It’s worse than when he was a newborn. He just wants to be nursing and if he doesn’t feel the boob in his mouth he cries nonstop. He now hates his binky at night, oh and he hates his dad at night. Super attached. How are all is anyone having their baby sleep through the night. I even tried letting him CIO and he wailed for 45 mins straight. I feel utterly defeated. I am newly pregnant again, could this be it?
