(((hugs))) if he's OT I totally agree, get him to sleep by any means necessary. Sh-pat can wait, til you are both less tired and stressed.
A wind-down routine can be really short. As long as it's the same steps, in the same order, every time. Ours was:
30 secs looking out the window
walk upstairs
change nappy and swaddle
close the curtains
song
into bed
the whole thing took maybe 4 mins (unless it was a messy nappy) and I would skip the song if he was fussy.
Have a restful weekend!!
