My daughter is the queen of bad sleep. She still wakes up at least once a night. Now I have heard of night terrors. A friend of a friend's daughter seriously had them. That is something different then what my daughter experiences.  You couldn't wake this child. It is a nasty thing to have to endure. I will ask what they did for them. I think they just outgrow them. Knock on wood my daughter has not had the plain nightmare wakings. She would go through weeks with those. Now she just plain wakes up. I will post later after I call my friend to see what they did..
