My kids have all had active shooter drills since elementary school (so sad) and are now in middle school and high school and still have frequent active shooter drills. Parents are notified every time. It's been going on for at least a decade. I'm in NJ.I wonder if it is appropriate to discuss school shootings with elementary school students or not. Maybe if they bring it up.
Although, when I was in elementary school, we had "nuclear bomb" drills. As if that isn't mentally disturbing, I don't know what is...
Edited to add - and my kids and their peers have also discussed school shootings since they were in elementary school. My kids all know about them, discuss them, and are heartbroken and anxious about them. It's tragic.
