Have you tried an ok to wake clock? My son used to drag out bedtime too... kept getting out of bed and screamed at the door. We got the clock with the dog and ball that turns red and green (amazon). Red means stay in bed and green means go. We got door knob covers too so he couldn’t come out of his room. With our baby monitor we would just remind him that red means stay in bed and that we wouldn’t come into the room until the ball turned green and he would eventually go back into bed. Cry a little bit but lay down and go to sleep.
