It's always hard to know what part of conjoined twins are seperate and which aren't. Was there two brains, or did the one brain adapt to both accomidate both faces? Sadly, we will never know. Like both of you, I agree that seperating the one from the fully developed baby was the right thing to do. In medicine there are many situations where the choice of one life over the other must be made. In those rare, but very real situations, the choice should never be taken lightly, or shrugged off easily.
