Q: In a recent column, you identified toddlerhood as “the hump of parenting.” As a grandmother who managed to raise five kids who were out of the house in their early 20s and are responsible citizens, I could not agree more. Two of them, however, did not get over the hump with their kids and now have spoiled, difficult children whom I sadly do not enjoy being around. Do you have advice for how parents can recover from this condition with school-age and teenage children?
