Bedtime issues

She just came to me where I was working. Distress all over her face. "I'm having trouble getting to bed," she said, through tears. "I think I'm supposed to be doing something but I don't know what." I asked if she needed help and she nodded. I walked her upstairs and didn't see anything that she might have been working on. I told her there was nothing she was supposed to be doing. I walked her to the bathroom and told her to brush her teeth, put on her pajamas, and go on to bed. She was okay then. This feels like a whole new level of the disease.
