I am shocked!  The boys were delivered by C-section (with me having been given an epidural) and I was told at the time that there were two sacs and two placentas so it seemed highly unlikely that they were identical - yes, they resemble each other a great deal but I felt there were sufficient differences to substantiate my original assumption.
