Sleepless in Denver

My oldest child - age 5 - gets up at least two times a night. We have exhausted every idea in the "parenting 101 books". But the child needs sleep! And so do I! Although she is up only for a few short moments - to go potty and ask me to tuck her back in, or to tell me she had a bad dream (and ask me to tuck her back in) or tell me there is something scary in the hallway (and ask me to tuck her back in), I am up for quite a bit longer after that. Short of drugging her, I need a few more ideas. I am going to re institute nap time for her. School makes it tough but the child needs her sleep. Small bumps during the day become major calamities (for her and me). Anyone else experiencing this issue?
