Lost in the many revelations and and explanations in the Jim Bob and Michelle Duggar interview with Fox’s Megyn Kelly was a bombshell comment made by Jim Bob Duggar stating that parents they spoke with had experienced “similar situations” within their own families.

As the Duggars explained why they didn’t seek professional help for teenaged son Josh after he admitted to molesting five young girls – four of them his sisters, including one who was reportedly only 5 at the time — they said they reached out to their church and friends for advice.

That was when Jim Bob offhandedly mentioned the feedback he received from other parents –presumably from within their inner circle — as they attempted to keep the potential scandal under wraps.

“It was a very difficult situation,” Jim Bob explained. “But as we talked to other parents and different ones since then, a lot of families have said that they have had similar things that happened in their families.”

According to John V. Caffaro, a professor at the California School of Professional Psychology, Los Angeles and author of Sibling Abuse Trauma, sibling sexual abuse is more common than people believe, saying it is almost at epidemic levels.

Writing for the Washington Post, he said, “Sibling sexual abuse is the most closely kept secret in the field of family violence. More than one in three cases of sexual assault against children in the U.S. are committed by other minors.”

“A 2002 study by the U.S. Department of Health and Human Services found that at least 2.3 percent of children have been sexually victimized by a sibling. By comparison, 0.12 percent are sexually abused by an adult family member,” he wrote before admitting that young children are naturally curious about their bodies.

“All children explore their bodies and may engage in visual or even manual exploration of a sibling at times. This is one way that children discover sexual differences between boys’ and girls’ anatomies.”

While that might explain sexual curiosity — such as “playing doctor” — in younger children, Josh Duggar was 14 at the time the series of molestations began.
