Still, as a mother who wants to make sure her children are safe and happy, I worry. And I think back to how I might have done things differently. Parents should decide for themselves what works for their family, but I probably would have waited longer before putting a computer in my children’s pockets. Phones and apps aren’t good or bad by themselves, but for adolescents who don’t yet have the emotional tools to navigate life’s complications and confusions, they can exacerbate the difficulties of growing up: learning how to be kind, coping with feelings of exclusion, taking advantage of freedom while exercising self-control. It’s more important than ever to teach empathy from the very beginning, because our kids are going to need it.
