My 6 year old granddaughter has a problem with her privates smelling bad. She has to take two baths a day to keep the smell from offending other people. She has been to the doctor about it and the doctor said she has a chemical imbalance. She is wanting to put her on birth control. My daughter is completely against that. Do you know of a natural way of balancing her out? She was told there was a type of vitamin she could give her to do it. Anybody know what it could be?...
