Pov: (denmark) No SoMe, no smartphones - until 5th grade (class agreement and school policy).

No SoMe at all for kids under 13.

No messaging after 20:00.

1.5 h screentime (ios) maximum a day.

O.5 h enforced reading (actual books) from 17:30-18:00 (we make it a family thing - all reading together).

No screens at all at playdates until 4th grade.

No movies or media below age-level ratings without consent from parents.

No phones in bed or while sleeping.

Heavy utilization of screentime, unifi network blocks etc.

Works well for us
