Since babies can't communicate verbally, they are actually far better at picking up on visual/facial cues than most people think. At just a few months old, babies can easily distinguish between happy and sad faces. Being able to empathize with those emotions helps the baby bond to the adult, increasing its survival rate from an evolutionary perspective. Fabian Herrera was playing around with his 3-year-old daughter Lucia, who was jumping on his stomach. He started fake crying to calm her down and that's when 6-month-old Aris started crying right along with him in a touching display of empathy. Fabian decided to record the special moment, which quickly went viral.
