Very, very little for DS4. Preschool shows a video on Friday afternoons for the "extended day" kids, when Grandma is babysitting she'll let him watch a bit so she can get a break, but on average, I'd say, less than 60 minutes a week.

When he was younger,we were occasionally tempted to turn it on so we could get things done, but now he can generally find things to keep himself busy.
