This is the tactic we are using: set a good example in front of our kid. If you don’t want your kid glued to phones and tablets, don’t be glued to phones and tablets yourself. I deliberately keep my phone off when the kid is around—don’t be seen using it. Set a positive example for her to follow. Lots of her friends are already addicted to phones, and if you go meet their parents, lo and behold, the parents are addicted too.
