I've reflected on this quite a bit, and why this thread has made me feel uncomfortable. There is, in some posts, a whiff of, 'hiding the disabled children'. Let me explain...
I share the pretty much unanimous view that its attention seeking and crass to share ambulance selfies and A&E pics on fb. Equally, sick bowls, kids in ICU, or very obviously being very clinically unwell at that point.
But, there are thousands of families whose lives involve living in or virtually living in hospital. Kids that never actually get to leave. Kids who have achievements the same as any other kids (or ones unique to their situation).
To their parents, that's not a hospital facebook picture, but their child celebrating Christmas, or their birthday, or as above, their first smile. Most first smiles don't come with medical devices visible, but some do, and those pictures are just as precious. To some families, managing a play in the ward playroom is as much of a special event thing as a day out to a theme park. They are allowed to share photos if their child's happiness just as much as if their child wasn't disabled or iniured.
Should children that are chronically ill be hidden away because its uncomfortable for other people? Because some kids will always be sick. When my daughter had an ng tube, and was therefore visibly unwell (her illness is largely invisible now), should I have refrained from pictures because there was medical equipment? What about kids in wheelchairs?
Where pictures dont infringe on their dignity any more than any other kid (if you disagree with kids on fb, thats a much wider question), censoring what us allowed feels very much like squeamishness over disabled kids.
