I remember watching an ultrasound of my first daughter. We watched her raise her thumb to her mouth, miss, and poke herself in the eye! It was hysterical! “It” wasn’t “it” any more. That was MY daughter. I went back to work the next day and told anybody who would listen – and a few who wouldn’t – about my daughter.
Unfortunately, if someone is set on resisting the truth, even something so convincing as an ultrasound won’t make a difference.
