I just noticed there were replies that referred to my reply.
It is difficult to share all the intricacies that went into our conversations about this topic, but yes, I know the kid wasn't uncomfortable b/c we kept discussing it afterward and he told me he was fine (the level of discussion in our family is such that I questioned that and approached him about it, again) and he understood my perspective.
Maybe that would not work for other people in their families, but it worked for us in ours.
We have lots of instances in our family (since there are so many of us) where we have to clearly discuss boundaries and when it's okay to force "my" beliefs onto someone else. (Actually, I would hope this is normal conversation in any household, regardless of size.) In the case of nudity, I do not believe it's okay to force my beliefs onto someone else and I also don't believe it's okay for someone else to force his beliefs onto me. Hence discussion and a resolution that works for all interested parties.
Interpret how you will. If it doesn't work for your family, I understand. That does not make it inherently traumatic.
It's interesting that folks would assume that an 8yo would be traumatized and lose trust in his mother from the little bit I wrote about this here. I think we could agree that communication involves sometimes uncovering the real root of discomfort in a conflict and if that root is gotten to, I think a workable resolution can be acquired. That is the point of healthy communication. I know, though, that not everyone practices healthy communication, even on message boards.
