Dear Amy: Six years ago, my two grandchildren were playing “family” in a makeshift fort with blankets hung for walls. These two cousins were both 6 years old at the time. Sometime during their play, clothes were removed and my grandson kissed his female cousin’s bottom. Since then, my daughter-in-law sees her daughter as a victim and her nephew as a sexual predator. The kids are now 12, and have never been allowed any time without adult supervision. We have a large family.
