DD is on day 6 of chicken pox. Everytime she sleeps she wakes up drenched in sweat and then screams and cries for about 10 mins. When awake she plays a bit but mostly just wants to lie on sofa and watch tv. She's not eating much either. Her spots are starting to scab, and she doesn't appear to be getting any new ones but she just doesn't seem any better in herself. Is this normal for this stage? Thanks
