Thank you for your question. It is my privilege to be able to help you.
The normal "physiologic" vaginal discharge starts with puberty. That usually occurs between the ages of 10 and 16. Diuscharge before puberty usually represents a problem such as an infection, a foreign body, or a rare tumor.
I hope you find this helpful. If you have any more questions please feel free to ask me. If you are satisfied, please remember to ACCEPT the answer so that I get credit for my work. BONUSES and positive feedback are always appreciated. Good Luck! Dr. SaulJE
