Bree’s usual bedtime is 9:00 P.M., and their parents enforce this rule. One evening, Bree is watching an educational program that ends at 9:30 P.M. They ask their parents if they can stay up to watch the end of the show. Their parents agree to let them stay up as long as they get up in time for school in the morning. Which parenting style are Bree’s parents demonstrating?
