Trouble going to sleep

My little boy will be 25 weeks tomorrow. He has always been SO easy to put to sleep, but the last few days for us have been absolutely miserable. He screams and screams... when I’m holding him, when I put him down, no matter what I do. I’ve tried longer wake times, shorter wake times. I cannot figure it out but it’s wearing on me so hard. I’ve had a couple of breakdowns in the last few days because my anxiety is so bad and this makes it way worse. Is this just a phase? I sure hope so... and a very short one at that. I can’t do this multiple times a day 😭
