The emotion of shame typically doesn't appear until toddlerhood. Shame is a complex social emotion that involves a sense of embarrassment or self-consciousness about one's actions or behaviors in front of others.
It is linked to the development of self-awareness and a growing understanding of social norms and expectations. While infants and very young children may experience basic emotions like joy, sadness, and anger, more nuanced emotions like shame tend to emerge as a child grows and becomes more aware of their actions in a social context, which typically occurs during toddlerhood and beyond.
