Hello! Our child has been having night terrors for quite some time now, almost at the same time every night. They scream terribly and it's very difficult to calm them down. They wake up in the morning as usual. But at night they cry all over the house and sometimes squeeze their legs. They don't answer any questions, they just say they hurt. But during the day they are an ideal child. Has anyone ever experienced something like this? We had something similar in spring, but they didn't sleep practically. We were given magnesium and a sleeping syrup.
