it is not unusual for your daughter to be afraid and want to sleep in your room, it actually is very common let her sleep with you, most parents will tell you their children are in the parents beds for a few years, if they were honest, and there is nothing wrong with that, they eventually head back to their rooms--although there HAS to be something, or someone who has scared her to this extent --is she watching the wrong things on tv?? they hear and store EVERYTHING, so if you are anxious about these things she will easily pick up on them--this is the age also of night terrors. Do you have the tv on the news channels, they hear it and do not understand alot of it but will remeber it all, commercials for upcoming movies might frighten her--ask her teacher they are great for getting the right info--is there a grandparent, uncle, aunt,babysitter, neighbour, etc., who has told her things that might upset her, thinking they are saying it for her own good--It HAS to come from somewhere so keep an eye on all things, but let her stay in bed until she is comfortable--what happened in her room?? did she hear about someome being taken from her room on the news ???? something always sets it off--letting her stay in the room with you is MOST common for sometime, wait until she has gotten over this, and slowly let her stay in her room with someone with her at first, and with night lights--it will take baby steps but it will work--anything in her room or closet that looks scary, get down at her level and look around during the day and at night, can she hear things in her room from anything in the house or the neighbours?? This is a time when scary things start to get into their heads and even more things they hear which they do not understand and put a young childs spin on it--good luck, would NEVER hurt to talk to teachers (as they have heard everything )her doctors anyone who deals with young children---my best of luck to you---one other thing is she around when you are talking on the phone about unpleasant things, either at home or on the news?? Baby steps ---bye for now--onemore thing any video (childrens or other) games that she plays, even though not scary , some children and people the anxiety of it does not help---
