no it is not common but three year old can certain develop a vaginitis from their common bacteria (usually the bacteria in the colon). because of the close proximity between the vaginal area and the anal area coupled by the questionable hygiene that three-year olds practice i often will see a bacterial vaginal infection. this is not the same a bacterial vaginosis in a sexually-active older woman.
is bacteria vaginosis common in 3 year olds?
