I don't know if I follow your exact philosophy but one thing I've never done: baby talk. Kid talk? Whatever you want to call it.

I talk to my kids like I talk to other people. "Go to the bathroom" is the notable example. By no means a pro and many flaws in my process.

Frankly, I think the best thing you teach them is not how to do or not do anything but instead the implications of thoughts and actions and what it means to handle and feel comfortable with their choices.

Mine are 8.5 and 4.5. They watch TV like plenty of kids. Rarely used iPads, and my older kid uses a laptop here and there. I will not let them use my phone casually.

But I don't think that them not using it is teaching them much about the phone. Instead it's about opportunity. Do something else! READ, draw, write, sketch, paint, run, craft, build, talk. I'm working on teaching my oldest how to be, well, bored.
