Night terrors are not remotely normal. They are a fairly uncommon and extreme sleep issue. My experience/understanding: Very bright kids get night terrors when you make sure they are physically tired enough to sleep but fail to make sure they are mentally tired enough to sleep. You need both to sleep deeply and bright kids who can't yet read have trouble reaching a state of being adequately mentally tired. I suggest you join some parenting lists for people suffering from having made the mistake if giving birth to bright kids. Tagfam.org is probably still a good place to begin trying to find support resources and reliable info. Edit: Bright kids are known to be prone to a variety of sleep issues. I spent twelve years arranging every minute of every day to make sleep feasible for one of my kids.
