A new study out of Singapore adds to what is a growing body of evidence that too much screen time is bad for kids, especially toddlers. Too much time staring at glowing rectangles like tablets, phones, and TVs, can stunt both physical and mental development of two- and three-year-olds.

In other words, regulating what our children see on screens is only one part of the equation. The other part is how much time they spend on screens. Healthy children need physical activity, sleep, and time to explore the real world. Virtual reality is not an adequate substitute.

On the new Colson Center podcast “Upstream,” my colleague Shane Morris talks with AXIS.org president David Eaton about how to set boundaries for screen time for our kids, and how to engage the ideas and culture kids will encounter in our brave new digital environment.
