I didn’t dismiss anyone’s trauma, I’m asking if that has ever resulted in anyone’s trauma
How can I speak for every person? Has it caused someones trauma? Yeah I bet it has. You initially made it sound like you were showing bath pics to every teen-aged first date that came over which would obviously be pretty fucked up.
showing the partner the first couple of pictures of the kid as a baby should be acceptable to people just as a “this is what they looked like when it all began"
Yeah we agree, baby pics are fun, I especially like noting family resemblances as everyone ages. My sister made my mom a big set of scrapbooks/albums for each of her kids one year, no naked baby pics were included. They're great fun to look at, highly recommend.
They also are unable to understand the concept of consent, let alone give it.
This is the primary issue, without even going into the obvious power dynamic between child and parent when it comes to consent later. Where do a childs rights end and parents begin?
I would also suggest that if that did cause someone trauma, it would be because the parent was aware this sort of thing would upset their child to that level and did it anyway.
I would suggest that most parents think they're doing great doing it just like it's always been done (i.e. generational trauma) and "they turned out just fine." but there are definitely some intentionally abusive ones too. The child with the intentionally abusive parent is obviously going to have way more trauma.
I think most parents wouldn’t actually show the pictures if they knew it would cause the child real psychological pain, because that isn’t the point in doing it.
The "real psychological pain" part makes it look like you're dismissing trauma, just because it's not something you experienced doesn't mean it isn't valid and while intent matters so does the result. I'm sure you specifically are a good parent and you're very conscious of your kids mental headspace but by default I'd say save it for the fiance if you just have to have them.
