21 month sleep help

My son will be 21 months in a few days and every since the 18 month sleep regression WERE STILL STRUGGLING and I just don’t understand. He’ll no longer go to my husband, wakes every hour to two hours, wants to nurse LITERALLY all night long, fights his crib after a couple hours and he’s always slept in his crib at night (nap is another story). Now the last 3 night I can’t even get him in his crib. He falls asleep on me and every time I lay him down he stiff bodies me and the process restarts. I DONT KNOW WHAT TO DO! This is getting sooooo hard! Does anyone have any advice, info, solidarity? I won’t do CIO.

Thanks for listening!
