The cases you mentioned above are just exceptions, not the norm. How often does the issue of chimera or swapped babies happen? Maybe 1 out of a million, I don't know

Yes, they are exceptions as you called it but it happened, and the effect of not considering those exception in relation with other factors before making a final conclusion as we have seen in many cases here is brutal and unhealthy.
