My DD used to have night terrors. She would scream and/or cry for an hour suck between awake and sleep. I could not calm her down or wake her up.
Sometimes, not often, it would help if I walked her around outside.
It was just a phase for us, it lasted about 6-12months.
I did hear somewhere that children are more likely to have them when overly tired or if they are overdressed and sweating during the night, Don't know if if it's true or not, but could be something to look into?
I don't have any mircale advice but you definately have have my sympathy
