The illusive full nights sleep

It was so cute the first time I found Elsie standing up in her crib.  I yelled down to Texas to grab the camera.  That was last week.  Now I'm in a loosing battle with my 7 month old.  Every time you lay her down she stands up.  EVERY TIME.  It's insane.  Crying and crying until you pick her up.  The biggest issue?  She doesn't know how to get down.  Dear Lord, this is NOT cute.  My sleep is constantly interrupted because of her compulsive climbing.   I'm not even sure that she's awake when she starts climbing.  Is it possible to sleep climb?  Could I have the only baby who climbs in her sleep?
