5 year old waking up in the middle of the night

[Guest guest]

Hi there. I haven't really posted much until now, but I have a new

issue that has popped up. Tabitha, who is 5 and had been a great

sleeper till now, has begun waking up in the middle of the night and

not going back to sleep for one to two hours. She is chatty-Kathy the

whole time, then she'll shut off and go right on back to sleep. She is

awake (I run a sleep diagnostic testing lab, so I am pretty up on the

sleep-walking/parasomnia thing) and she expresses fear of being alone

or of the closet, but she askes me to dim her nightlight - kinda wierd,

no? Anyone have this experience?

Thanks!
