He may be having what they call night terrors. Our son had them almost daily at night-time and during naps for sevral months from about age one to 2 1/2. Then it stopped for awhile and started up again for a very short time ,then stoppped again for over a year. He is now 4 1/2 and has been having them again nightly for the past 4-5 weeks. I asked the peditrician about it; he said often it comes from being overly tired or sleep deprivation. He gave me a write-up on it. It says very clearly that they are not awake during this time; it is basically like sleep walking. You are not supposed to try to wake him up. It says to try to hold or comfort them, without forcing yourself on them. Offer to hold his hand and reassure him that momma and daddy are right there and that you are all safe together. They can last anywhere from a few minutes to about 40 minutes. Also, they usually occur in the first 2 hours of sleep. Our son has his almost like clockwork...usually within 40-50 minutes after he has fallen asleep. It also says to maybe turn on a low light so that shadows don't scare him...because even though his eyes may be open, he is probably not awake. I know it is frustrating...it upsets me everytime our son has one..because he appears to be petrified each time and he trembles uncontrollably with fear. Sometimes he tries to run thorugh the house screaming NO! NO!. Last night he appeared to be trying to open our bedroom window. Very scary...stuff. Do you have access to a fax? I can fax you the literature our pediatrician gave me, or you can ask your pediatrician about it. Let me know if you would like what our pediatrician gave me on it; it may help you identify the episodes, help you with how to handle them, and give you some relief. Or I couldmail you a copy of you like. Let me know. Good luck and sleep well.
