We have been doing nighttime sleep training for four days with absolutely no improvements. The crying lasts about an hour and a half and she always wakes around midnight to cry and just be awake for another two. We do checks when she's hysterical hysterical but other than that she just lays on her back screaming showing no signs of self soothing attempts (despite having a half dozen pacis, a lovie, and a blankie in the crib with her.) is this normal to see no progress? This is awful
