I’m thinking back to when my girls, now 6 and 7, were just a few months old. “Delicious” is the word that most immediately comes to mind. As I spent countless hours — like any new mom — looking adoringly at each of my daughters’ chunky cheeks and dreamy eyes, I often wondered, “What is going through your mind?”

Turns out, maybe a whole lot more than I realized.

According to researchers at Yale University’s Infant Cognition Center, also known as “The Baby Lab,” babies can actually tell good from evil, even as young as 3 months old. That research is the focus of a three-part series this week on ”Anderson Cooper 360,”which airs weeknights at 8 p.m. ET.

To the skeptics who say, “Come on, how can an infant tell the difference between a good guy and a bad guy?” — I can relate. It certainly runs counter to our notion that children are born as blank slates and learn right from wrong entirely from us. . .
