Hello again I put my son to sleep at 12 and recently barely woke him up He was generally crying in his sleep for a long time, I thought about calming down but he started to cry loudly ? straight away and everything would be fine if he hadn't been acting like that in his sleep, I barely woke him up and after waking up, he took a long time to come back to himself Has anyone had this happen? Is it normal? I got scared when he didn't wake up and cried loudly
