‘It went nuts’: Thousands join UK parents calling for smartphone-free childhood
(www.theguardian.com)
Depends what you mean by "it worked". Of course the kids play too much games and watch too much YouTube. But at least I have kids that are happy and I really have fun with.
It's also easier to tell them what I want when I really need them to do something. What I want to avoid is to have kids that don't have respect towards their parents.
I guess it's also my attitude. I really like to come back from work and have fun with my kids and see them happy. I know many parents who rather try to get their kids to sleep as soon as possible to have time for themselves.
