Many parents don’t feel comfortable giving their teens some freedom during a family trip, according to a new poll.

It’s natural for teens to seek more independence, but parents sometimes are hesitant for a number of reasons, including safety. The new poll from the University of Michigan has found parents of girls are significantly more likely than parents of boys to worry about their teen being approached by a stranger, becoming frightened. C.S. Mott Children’s Hospital poll co-director Dr. Sarah Clark told us more.

“One of the things we sort of laughed about was where parents differed in their concern for teen boys was that they’ll do something dumb,” Clark said. “Guess what? Yeah, they will. But sometimes it’s like that’s part of the learning experience.”

Clark said it’s good to set boundaries with kids on family vacations. So some rules could include a teen checking in by phone or asking them to stay with friends or siblings.
