If you're a parent, grandparent or guardian, the following signs may indicate your child has been molested, according to the National Center for Missing & Exploited Children. Some of these behaviors may have other explanations, but it is important to assist your child no matter what the cause. Also, keep in mind that children do not always demonstrate obvious signs, but may do or say something that hints at the molestation.
