My 15 month old son appears to be having night terrors occasionally. what is the best way to handle night terrors? is there any prevention techniques?

See Your Doctor: Sleep Terrors=intense arousal state of confusion, fear, agitation, sweating, rapid HR/breathing, & more. Common in pre-school/school ages. (3 yr olds & up). Child is unresponsive to comforting, may not recognize parent, has no recollection after awakens. Attempts to wake child can prolong event. Precipitated by stress, inadequate sleep, & more. Due to child's age, see doctor for correct diagnosis.
