Actually... A friends sister died ina Dentist office. She was in for a root canal, and had an allergic reaction to the shot she was given. Since it was in the Dr.'s office they weren't equiped to deal with the serverity of the situation...
But that's a topic for another discussion....
As for my children, they are never out of my site. If a Dentist or Dr. wouldn't let me in the same room (except for x-rays where I waited outside the door) I would leave with my daughter, and find someone else. I have even brought my younger daughter with me, when my older daughter was having blood drawn. The girls, and I
, are always well behaved, and I have not run into a situation where they have frowned on my following on me being in the room.
