My parents did not allow a TV in our home until I was 8 or maybe 9. And even then I was only allowed very short viewing times during the week days and week-ends. I had books and comics, toys, board games and actual friends to play with, at home or, brace yourself, outside and without any adult supervision.
Sure that happened many decades ago, in the previous century. But it did not kill me, far from it.
edit: The key thing is that my parents too had other activities than watching a screen. Things I watched them doing and that I naturally tried to imitate.
