Similar experience here. Both of my kids have unlimited screen time and they don’t really watch all that much. I think being able to watch as much as they want makes them bored of it. In fact, they constantly ask me to play with them instead, which if I’m not super busy I try to do. 

 I think you don't realize that them asking you to play is a symptom of the dependency screens create: they are not used to playing by themselves, they constantly need someone to distract them
