Crying 3 week old

Kelsey • Love my kids more than anything ♡♡♡
I am a FTM and my 3 week old recently started having screaming fits. They started around 10 pm and went on for 2 to 3 hours. Then now they are starting to happen not only at night but during the day time too. Has anyone gone through this?? She is inconsolable during these moments. I try Binky, bottle, rocking, walking, dryer, car rides, bouncing, laying her on my stomach sideways and waddling around, putting her on my chest, nothing works. I had luck with her lessing on my stomach and putting her on the dryer in her carseat once. Other than that, nothing has worked. Today she had 3 screaming fits, I feel so lost and frustrated at myself. She hasn't really been sleeping lately either. She also has a really hot head but cold cheeks. Anyone have any advice?? I am dying here, I'm slowly losing more and more sleep and sanity.
