Imagine you're standing in a grocery store when a baby looks at you, smiles, or waves. Many people instinctively smile back, make a funny face, or say hello, even though they've never met the child before.
Psychology says this reaction is surprisingly common. It doesn't necessarily mean someone wants children or has a naturally outgoing personality. Instead, research suggests that babies possess physical and behavioral traits that automatically capture human attention and activate emotional responses linked to caregiving, empathy, and social connection.
