We have a similar approach to ABQMom. DD has days where she just needs to veg and she'll have a few hours screen time over the course of a day, but a good majority of the time she has very little interest in screens at all. She'll turn something on only to switch it off 15 minutes later. We kind of go with the flow. I agree with Dude too, that screen time limits are more about ensuring kids are getting their social and physical needs met - which dd definitely does.
