Prevalence of Child-on-child sexual abuse

The incidence of child-on-child sexual abuse is not known with any certainty, similar to abuse by adults. It frequently goes unreported because it is not widely known of in the public, and often occurs outside of adults' supervision. Even if known by adults, it is sometimes dismissed as harmless by those who do not understand the implications. In particular, intersibling abuse is under-reported relative to the reporting rates for parent-child sexual abuse, and disclosure of the incest by the victim during childhood is rare.
