I'm aware that if I don't have some "rules" in place now (i.e. a the tweenie stage) it will be very difficult to change things once the dcs become teens. But I'm seeing a gradual creep in time that the dcs are spending on screens and feel like I am now starting to constantly be battling to get them off the screens and having negotiations when they find reasons they "need" to be on the computer/ipad. Can you share the rules/guidelines you have that you feel work (or indeed any you wish you had put in place before your dcs became teenagers)?
DS14 and 12. Both spend a fair amount of time on screens but are both 'top set' boys in school and doing well at that. Never in trouble, homework done, work on target, they play football, cricket and do scouts. I have learned to chill a little about the whole screen thing. I remember spending hours on the ZX Spectrum back in the day and still did well at school, going on to uni, had plenty of friends etc. The only thing I'm strict on is sleep. Phones are allowed to be charged in rooms overnight as a matter of trust, but put away half an hour before bed and if found sneaking on them will be removed overnight from then on. And we do check!
