I had this issue when I was young like crazy! Sometimes it was so bad that it would crust in my pubic hairs....very uncomfortable. You're lucky I don't get embarrassed easily....here's why I think I was having the issues. I've read that discharge is a sign of molestation. Well, when I was in about the 3rd grade, I was spending the night with a friend whom I saw masterbating when I woke up in the morning. I was very curious, so after that, I tried it myself. Once I felt how good it felt I began doing it all the time, basically out of boredom. So, this is obviously the reason for my discharge back then. If your daughter is doing the same, it could be the reason. I would talk to her. I wouldn't come out and ask her, but I would give her a couple of reasons that can cause it. Something like "You know, I know you're wondering why this is happening, and here are a couple of things that have caused it to happen to other girls." Atleast then she'll know why, and if those two things aren't the reason, think about changing obgyn's, so you both are comfortable enough to ask these sorts of questions.
