What Is The Significance Of White Vaginal Discharge?

my daughter is 11 years old. She recently told me her labia minora has been getting larger. When she showed it to me i also noticed that her clitorus was covered with a flap of skin almost all the way. She was not like this when she was born. Today she tells me that white stuff is coming out of the clitorus and refuses to go to the doctor. What is this and what should i do?
