I care a lot about my children's privacy. There are not many settings in which I would allow them to be naked, but a very small number of situations, yes. I'm not outlining the ins and outs of how I make that decision, but please be assured that I do not take my children's safety lightly.
There are multiple people on this thread, including me, who "work in safeguarding" (starting to hate that as a phrase to be honest) and/or have first hand experience of abusive situations. The fact that many people with experience in this area are disagreeing on this particular topic shows that it is not a clear black and white situation.
Risk assessment is not about removing any situation where there could be harm. It's about mitigation and balance. I understand the temptation to see harm everywhere in this job, I really do. But that can be a sign of vicarious trauma, and can be harmful in itself.
Regardless, the point I made to Wendy and I make again now, is that it's possible for reasonable people to disagree on something without resorting to insults, calling each other liars, assuming poor parenting, etc.
