From what I've read, most known damaging screen time studies have been with non-interactive TV and extrapolated to other digital screens. I'm under the impression there will be more screen time for my kids than there was for me and I try to steer that towards problem solving and interaction, as opposed to consumption time. My daughter (3) loves to take pictures with my phones and tablets and crop, color, add the silly effects. Somehow ( and probably misguidedly) I view this as better than putting her in front of a movie.

In my view, it is probably more important to control the specific activities more than the blanket "screen time".
