Danny CarltonI didn't comment before in case I offended someone, because I felt the issue seemed to be overblown. Now I see what you are talking about. I am always present when my children are examined, and there's no way I would allow most of that to happen to them. When my kids' Ped Endo had only one intern assisting he asked permission for the intern to be present.
It seems to me it's also a matter of parents taking charge and not allowing doctors or interns to treat their children as exhibits. This then would establish to the children that they also shouldn't allow that kind of behavior. People will treat you with whatever level of dignity you demand of them, the key is to make sure, in no uncertain terms, exactly how you expect to be treated.
In every one of your examples, while the doctors showed an incredible lack pf professionalism, you were still in a position to demand it of them. Of course not too many 10 year-olds have the guts to tell a doctor how to behave, which applies to both my suggestion as well as yours. In that case the parent (still not necessarily someone who can be assertive enough to confront a doctor) needed to take the lead.
In example #2, you could have said, "Do you want me to leave while you two talk?" That would have shut them up, then you could explain that it is very rude to treat you as an inanimate object while you are in such a vulnerable position.
I teach my children that ther are common, ordinary parts of their bodies, and then there are special parts. Just like we don't run and play in the sanctuary at church, we treat the special parts with respect, dignity and reverence. We all need to remember that and just as we'd not hesitate to confront someone profaning the sanctity of a Church sanctuary, we also should not tolerate a doctor disrespecting the reverence due to those parts of our body that are special.
Funeral directors attend funerals on a daily basis, but they have the professionalism to still show reverence for the event, that to them has become commonplace. They understand that it isn't commonplace in the least to the grieving relatives and loved ones of the deceased. Doctors should be able to show the same reverence to their patients. And we should always demand that they do.
