What are your specific screen-time limiting methods?

Hi everyone. I've got a 5-yr-old who enjoys screen time (what kid doesn't) and that's totally ok with me. We just try to make sure she she has a larger quantity of non-screen time.Like most parents, we really want her to develop a love of spending her free-time reading, building, creating, pretending, physical activities, etc.... and not just resort to screens whenever she's bored.The thing I'm struggling with is that it feels really arbitrary to me as to when we say yes to screens and when we say no. I'd love to have a system that we all can buy into.Instead of something as simple as "X minutes per day," I was thinking of doing something like this: She gets a certain number of 15 minute "tokens" at the beginning of the week. She can use as many as she wants each day (put them in a jar when used) but they have to last all week. So this way she'll learn to spread them out which I think is a good skill.What system do you use? Any pros/cons you've learned along the way?What do you do when you have that occasional/inevitable day when you're tired/exhausted/sick and you let your kid binge a bit on screens?(We are also trying to teach her that screen-time is not a bad thing. It's just like eating a well-rounded diet. Your brain needs to lots of other kinds of activities, not too much screen-time. So hopefully the combination of all this will sink in.) via /r/Parenting http://ift.tt/2qfhtqq
