Five month old FIGHTING sleep.

My baby just turned five months old today but for the past month has had sleep problems. This week he has begun fighting his sleep! He screaaaamms when I try to put him to bed even though he's visibly tired (rubbing eyes, fussy, yawning). I try rocking him, swaddling him again, his pacifier (which he has to sleep with but won't take when he's in this rage), just putting him down.

He continues crying and it increases. Then he'll calm down for seconds like hes about to knock out then continues to scream even louder. I don't know what to do and I can feel myself getting really frustrated. Like why can't you sleep? I love sleep, your dad loves sleep, everybody loves to sleep! Lol

Any advice would be appreciated, I feel like I'm going out of my kind trying to figure it out.
