Night terrors are typical for 3 - 8 year olds, but the percentage of 21 mos having these are really small. That really brings a RED FLAG that would send me writing daily documentation of what has been happening in and outside the household since these started. Now, the case studies over the years have documented that they are typically inherited. Plus, a good way to confirm they are night terrors is to ask the 3 1/2 year old if they remember anything from the episode. That is the main difference between a terror and a nightmare. Nightmares are remembered, as night terrors are not. Although, not to throw confusion into the circle, but there are some small percentage reports that have been remembered and classified as night terrors. Most of them are not, so asking might leaned a helping hand in figuring out if it is one or the other. A nightmare is usually caused by episodes that day. Something in the environment upset the little ones. Unfortunately, there is no documented study that has a good explanation for why some children suffer from terrors while others sleep soundly through the night.
Here is my thought on the matter....and this is a simple theory of my own...
These are above average children, their brains are stimulated more so than other children, they might even be introverted children or children that do not speak to others about things that bother them, highly sensitive children, to the point of having a sixth sense about them, feeding off of others emotions. Maybe when the children go to sleep, this is the time when their brains awaken for some reason, start processing this unspoken language of events/concerns/emotions/images/etc., and the outward screams and cries and yells and walking is their brains way of processing and expelling this information.
The moms have good ideas of praying with the children before they go to bed, letting them know that love surrounds their little souls, letting them know that mommy and daddy are by their side always, but most importantly, not speaking to them during the episodes, and if they will let you, touch in a soft way (whatever soothes that particular child), holding hand, back pat, back rub, breathing next to them, etc., or just simply making certain the path or environment is completely safe during the episode.
One thought would be to place something special in their room. Letting them know that it is a symbol of their families bond between one another, the keeper of all good things, and the watcher of all bad things. Whatever the parents want to tell them...but, make it a special item...something the children will be able to relate to and look up to for strength and courage.
Good Luck!
