I don't have kids yet but it is something that has been discussed about my nieces and nephews. As you say, you don't want your kids to become social pariahs but you also don't want to give them smart phones, in this day and age it looks like the two are intrinsically linked, which is disappointing.

I would like to say that we can teach kids to have a healthy relationship with the internet and social media but sites like TicTok are engineered to be as addictive as possible so that would be naïve of me to say.

In saying that, if you outright ban these sites in your house it just means that when it comes time for your kids to be more independent they could possibly have no knowledge of how to healthily use social media and then be worse off than if they had access early.

There is no easy answer here, at the end of the day it will be their decision, all you can do is teach them to navigate the digital world and then be there to help when they make mistakes.
