Crib training help!!

Okay so my son has slept in a bassinet since birth. I would always burrito him in a thick baby blanket (please don’t shame me. He was 100% safe the whole time). Recently he became too big for his bassinet where it would be unsafe to use any further. I set up his crib. The first night he slept wonderfully. The second night I had to move him into my bed because he was too cold. Now he takes forever to fall asleep and wakes up around 4-5am screaming and won’t go back to sleep until he’s in my bed. I think it’s from him not being burrioted and being cold. I dress him very very warm but it’s his face and hands mostly that get cold. Plus laying out flat instead of cuddled in a blanket. The blanket isn’t an option because he rolls (even arms out because he will roll and pull it onto his face). What do I do?? 😭😬 it’s been over a week now. I’m losing my sanity. I am not comfortable sharing my bed with him so I need help!!
