@bencurthoys it's hard! Our kids have access to tablets but the time they use them is very limited.

I sort of plan that as they get older, we have some family pool smartphones, that they can use when leaving the house for the things these phones do well - maps, location sharing (with their consent once they are older ofc) - and on those I think whatsapp etc will be there, but on the understanding that anyone in the family might see it.

Teenagerhood does need privacy too, so will have to see...
