There's a fine line between controlling and teaching. I have never restricted my kids without reasoning and they almost always listen. If they retaliate, I sit back and let them have their way, so they can practically see what I was talking about. That said, every child is different and needs different treatment. My eldest always listens and the youngest sometimes have his way. I have never forced him for anything because I know his nature, he takes a little time, first he has to explore himself and then when he's ready he gives a shot to what others said. I think that's okay unless he's not in any potential danger (he's just 4).

As far as technology is concerned, you are right we should familiarize our kids with it but I strongly believe there's a time for everything.
