This is a very interesting and worthy concept and I'm suprised/saddened that it hasn't received the attention I think it deserves here. So BUMP!
That said, nakedness is something my husband is not shy about, though unfortunately I am (working on it!). We regularly sleep naked (how can one not in this wickedly hot weather), right alongside our son, and until now I hadn't a second thought about it. Neither, I'm sure, has my husband. Just seems a non-issue (though, he is only 4 months old, we'll see how it plays out as he ages).
I'd like more information on this, or to be pointed towards more info on it.
Googling now...
