Our social media is family and the sort of friends we would meet up with only - my FB friends list is under 80 and my husband’s under 60. Both of us have our settings so that unless you are on our friends list, you can only see our profile picture and cover photo. We can only be messaged by friends, or friends of friends - nobody can “add us” and, whatever you tag us in won’t appear on our walls unless we agree. We both agree that FB friend status should only be given to people that we would show pictures of our family to anyway… I have insta too, but that’s just full of pictures of my garden and cats!
On our child’s birthday we share 12 photos of him covering the last year on FB. We might make reference to him in posts - “eg “lovely walk in the sunshine today, DS found a secret path” but he wouldn’t directly appear in the photos of that walk, and that’s possibly a few times a year.
other people is more difficult…
My mum a few times shared pictures of DS as a baby/toddler, despite her asking her not to, but each time we reminded her. We’ve reached a compromise now where she has to show us what she wants to share first - the extra step of checking with us seems too much faff though as she doesn’t do it more than once or twice a year.
We haven’t stopped the school using his image - they don’t use names along side.
We haven’t stopped people taking photos of him with their children and sharing them incidentally - again, his name isn’t attached. And, we thankfully have like minded friends who tend not to over share anyway.
