Yes, and children experience emotions before they learn to reason or use language, so they have a personal basis to work from when learning to reason about the emotions of others. "Empathy" is the name of the reasoning process by which children analyze the experience of their own emotions and behaviors, to draw inferences about the emotional state of others based on observing their behaviors. But long before that, they are reacting emotionally to the behaviors of others. For example, you can scare a baby.
