It is possible if parents make it possible. DD wasn't allowed certain apps until she was old enough. She was allowed enough apps that she could play games and talk to her friends. She didn't have a smart phone until she was 11 and starting secondary school. There are kids as young as 5 being given smart phones by their parents.
I know the passwords to everything and can access her phone at any time. If she changes any passwords then I can take the phone away. She is 15 now and I trust her more, but she knows that I still have the right to access her phone.
We had a case of grooming in our family several years ago, involving a 12yo and a21yo and it actually went to court, so I have been very aware of the damage that phones can cost.
DD is 15 now and has no interest in TikTok at all. She can't understand her peers who are addicted to it and addicted to their phones.
If more parents put their foot down and made their kids get off their phones, it would make a huge difference. But a lot of parents don't care. A lot of parents are just happy that the kids aren't bothering them.
The change has to start with the parents. Check the apps, limit the time spent, turn off the wifi overnight, remove the phones from meal tables, insist on free time without the phones.
Yes the Government can step in and do something, yes the schools can go on about the dangers of social media, but it has to start with the parents removing the access/phones from the children.
