According to the psychologist Peter Gray, children today are more depressed than they were during the Great Depression and more anxious than they were at the height of the Cold War. A 2019 study published in the Journal of Abnormal Psychology found that between 2009 and 2017, rates of depression rose by more than 60 percent among those ages 14 to 17, and 47 percent among those ages 12 to 13. This isn’t just a matter of increased diagnoses. The number of children and teenagers who were seen in emergency rooms with suicidal thoughts or having attempted suicide doubled between 2007 and 2015.

To put it simply, our kids are not O.K.

For a long time, as a mother and as a writer, I searched for a single culprit. Was it the screens? The food? The lack of fresh air and free time, the rise of the overscheduled, overprotected child, the overarching culture of anxiety and fear?

Those things might all contribute. But I’ve come to believe that the problems with children’s mental and emotional health are caused not by any single change in kids’ environment but by a fundamental shift in the way we view children and child-rearing, and the way this shift has transformed our schools, our neighborhoods and our relationships to one another and our communities.

The work of raising children, once seen as socially necessary labor benefiting the common good, is an isolated endeavor for all but the most well-off parents. Parents are entirely on their own when it comes to their offspring’s well-being. Many have had to prioritize physical safety and adult supervision over healthy emotional and social development.
