I'm sorry you're going through this right now, hearing your baby screaming can be really hard, especially when they're never usually like it.

The only advice I have is from my own personal experience. I have noticed lately that DS cries when the bedroom door is left open a little & he gets a bit of light in his room. Now I close the door completely & he "usually" goes straight to sleep in the dark

I hope I've managed to help a bit
