It feels like there's been a generation divide where younger kids are not as insistent on smartphones as the older kids were. Maybe it was covid. But also there's a lot of negative sentiment even amongst kids about smartphones - that they are addictive, encourage anti-social behaviors, and enable bullying. "Brain-rot".
Our local school district banned phones during school hours just this last year and there has been an overwhelming positive sentiment from faculty and kids.
We don't otherwise do things like track screen time. Our kids have videogames and computers and tablets. But we're providing a dumbphone in late grade school and so far there are no protests to get anything else.
