Sleep regression

Ka

Going on almost 10 days or so of major sleep regression. He fights going to bed so much and what used to be a 15 min bedtime with a couple books and song then leaving the room and he going to sleep quietly on his own is now an hour of crying and squirming and fussing... I’ve had to sleep on the floor in his room to get him to go to sleep. He is still in his crib so it’s not the bed transition issue. He has been waking in the middle of the night lately too and crying hard so I am sleeping on the floor to hold his hand. I’m exhausted. Anyone else going through or just gone through the same?
