Middle Night Wake Up

Last night, Elana started hitting my leg.  I moved up my foot and the next thing I know, I have a head under my leg.  I moved her over.  She did not go back to sleep.  I checked the time.  It was 3:00am. That did not bother her.  She got out of bed and started walking around.  I checked her diaper.  She was soaked.  I changed her, but she was not ready to sleep.  I closed the bedroom door and tried to sleep.  When I woke, Elana was back on the futon knocked out.
