At what age did you start and why? I think we are mostly OK w/ DD having some limited screen time at some point in the future, but I have no idea when. She seems way too young now, but will there just be a time that feels right? That seems weird to me considering we are so accustomed to not watching TV. So did you carefully plan when you would permit TV time? Just try it on a whim one day? I'm just wondering.
