Indeed, adults were quite straightforward about such things back then. I remember, for example, crouching under my school desk during air raid drills. The hypothetical bombs in question were “atom” bombs, which, we were told, could come raining down at any time. I don’t remember any kids my age or thereabouts who were “traumatized” by such information. We trusted that adults knew what they were doing and would protect us as well as they could. We were also aware that “as well as they could” was no guarantee of safety. As Miss Langley astutely pointed out, that was a “healthful” thing for us to know. Kids talked about it freely, but not obsessively. We mostly planned what candy stores we would pillage if we survived.
The article then quotes a prominent psychologist as saying that anxious, frustrated, tense parents can adversely affect their children’s security. In turn, the children may develop various behavior problems. Mind you, many of the sorts of problems in question are today called “disorders” and children, not parents, are often medicated for them.
