maybe at 7 and 10 they shouldn't use device connected to the internet without your active supervision at all? What will they miss?
Would you say the same of eg: parents giving alcohol or smoking to their teenagers?
I would never tell another parent they were wrong for choosing not to allow their kids to use the internet or consume certain types of media. Those are very personal choices.
My wife and I have deliberately have chosen what to allow our kids to do, and continually have talks with each other and with the kids about our internet usage.
I don’t feel the need or desire to seek advice or approval from random internet commenters.
