My grandsons, age 28 months and 16 months, have been having night terrors since before their first birthdays. They are loved, well cared for, and healthy. Why would this be happening?

Night terrors are somewhat mysterious. It might seem as though night terrors are the same as a bad dream, but they aren't. Dreams occur during REM (rapid eye movement) sleep, a stage of sleep when the eyes move quickly and heart rate and breathing may be erratic. Night terrors happen during the transition between deep sleep and another level of sleep - it's almost as though the person gets "stuck" momentarily between levels.

The good news is that night terrors don't seem to have any harmful effects on the people who have them, and they aren't necessarily a sign that something negative is going on in their lives. Night terrors can happen to loved, healthy, and well cared for children - like your grandchildren!
