Sleep regression

Mamas I need help 😭 it’s been about a week or two now. My little one has always been a pretty good sleeper. He usually goes down anywhere between 7-8 depending on how the day went and our routine had never changed. Well recently he will not go to bed. It started on date night when my MIL had him. Ever since that night he will scream and cry in his room when we try to put him to bed. He has been falling asleep independently for months so this is very unlike him. I would just rock him to sleep but he throws a complete fit in the rocker and all he wants it to leave his room and be with us… he won’t fall asleep on me, not in my bed, not in the couch with us. We have tried it all and only the car works. ifs it very late and we put him in his room he will cry for like 30seconds to a minute and fall asleep but that’s only when it’s like past 10oclock, otherwise he will just cry and cry and I can’t do that. Also, he still goes down for naps normal with my MIL(she has him while I work) but won’t go for naps with me. Anyone have any tips or just experiencing something similar?
