I'm lucky enough to be able to send my child to day care where he doesn't get any screen time (obviously), so typically his only time he gets to watch something is when we are out and about, and even then we have a rule of timers before he can watch, or if we are at a tap house or something, we've made him actually have to sit and talk to people/friends, ask them how they are doing, introduce himself, etc. Once he does that, he can choose a Pixar movie of his choice or a live concert video to watch.
And even with all that, I still feel guilty due to the reddit mob telling me it's going to destroy his brain.
