This is called "contagious yawning." Contagious yawning feels automatic, like a reflex you don't have to think about. But scientists know it's not completely automatic because we are not born knowing how to do it. In fact, contagious yawning only starts around the ages of four or five, which is when kids begin to develop better empathy. Empathy means understanding and sharing the feelings of others.
