Terrible going to bed?

All of a sudden my little guy is terrible going to bed again. Screaming and crying momma it just breaks my heart. I’m being intentional playing with him lots during the day, taking him outside, checked his diaper, made sure he’s had the opportunity to eat lots throughout the day, Motrin when teething but every time before nap or bed he’s miserable and so upset. And the wake windows are fine cuz after screaming and crying for a couple minutes he falls asleep but it just breaks my heart I go in and tell him its night time and cuddle if it’s really bad but it’s every night now I just don’t get it 😭
