My daughter is talking in her sleep like she's stuck in some sort of nightmare. what should i do?

Depends: If she awakens to light touch it is a nightmare and light touch will bring her out of it.She will recall the scary issues. If it does not, the sleep talking and struggling movements are a night terror. These usually last up to 5 minutes and stop on their own.If awakened the kid does not remember any part of the event.It represents a sleep deficit problem and can be helped by increasing sleep times.
