Another thought for sleep....do you have access to an I-Pod and/or I Tunes? If so, maybe she could put together a list of songs that are relaxing to her. This helped my daughter. She said she visualized herself "floating away" on the notes. I just went through my daughter's "sleepy time" play list:

Jack Johnson, Frank Sinatra (?who knew?), Dean Martin, Beatles, Colbie Caillat, etc.
