Which developmental stage are newborns primarily in, as defined by Erikson's theory?

Newborns are primarily in the stage of Trust vs. Mistrust, as defined by Erikson's theory of psychosocial development. This stage occurs from birth to approximately 18 months and centers around the infant's need for consistent and reliable care from their primary caregivers. During this critical period, infants learn whether or not they can trust the world and the people in it based on their experiences of being cared for.

If caregivers provide warmth, security, and affection, the infant develops a sense of trust, laying the foundation for healthy relationships and emotional stability as they grow. On the other hand, inconsistent or neglectful care can lead to feelings of mistrust and anxiety about the world. Therefore, this stage is fundamental for the emotional and social development of infants, as it sets the stage for future challenges in Erikson's subsequent developmental stages. Understanding this is crucial for recognizing how early experiences shape a person’s lifelong psychological well-being.
