I ran my own test to see if JoJo was smarter than a two year old. I held JoJo in front of a mirror, as my wife quietly walked behind us and waived JoJo's favorite toy. JoJo calmly admired her beauty in the mirror and then within 5 seconds saw the toy and turned to get it! Yeah! (fist pump)...smarter than a two year old!
