I agree, and the "not the first time" I think is key there. Setting expectations I think is crucial. For ours (5yo), we're clear about what he can watch and for how long. We control the device. "Two episodes before dinner" or so. Over time, he learns how this works. And we're not afraid to tell him that now isn't a good time for the TV.

It's not to say we never have any complaints over this, but when we do, it's rare and usually because something else is amiss (hungry, frazzled, tired).

But most instances it's like last night, where we were clear that we had time for two episodes of Tumble Leaf before dinner. At the end of the second one he announced "last one!" and got up off the couch as we picked up the remote.
