Middle of the night crying fits 😭

My little 3 week old boy is absolutely an amazing sleeper during the day, but at night he goes on these crying fits where nothing calms him but a boob. And even then he unlaches and makes grunting noises. I wish I had someone to talk to during these middle of the night escapades, but all I end up doing is crying with him begging him to just go to sleep. Any advice?
