Our 10mo DD seems to have nightmares a couple of times a week. She appears to be asleep but will scream and is difficult to calm down, even when she has opened her eyes, she is still really distressed. Is it possible to be having nightmares at this age? I was prone to night terrors as a child, so I am not sure if this is heritable. If they are nightmares or night terrors what is the best thing to do for them?
