I am not sure if you are aware, but if you hold a newborn baby under its arm, it will make a walking motion in the air with its legs. This is likely the remnant of a legacy behavior that was useful a few millions years ago. I don't know how the test is called but it is part of the standard test protocol at birth. I am not sure if this is part of Agpar score [0] or called something else. [0] http://en.wikipedia.org/wiki/Apgar_score http://en.wikipedia.org/wiki/Apgar_score
