Some LOs just don't respond to apop. My DD was one of them. I could get her to sleep in a sling but only in a dark, quiet room which is silly really. Sorry, probably not what you want to hear.
I think as he goes through this wonder week, I would just try to make peace with the fact that he's going to be awake a lot. You can lead a baby to bed, but you can't make him sleep, yk?
