What is an example of a milestone in social-emotional development during infancy?

An example of a milestone in social-emotional development during infancy is developing attachment to caregivers. This attachment is crucial as it forms the foundation for a child's emotional well-being and impacts their ability to form relationships later in life. In the early months, infants seek comfort, security, and responsiveness from their caregivers, which leads to a sense of trust and safety. The development of this bond is essential for healthy emotional growth and significantly influences how infants manage emotions and socialize as they grow.

While showing anger responses, exhibiting curiosity, and learning to share are important aspects of a child's overall development, they typically manifest later in infancy or early childhood. Developing attachment is uniquely significant to infancy, marking a critical period where emotional bonds are established, and these early experiences shape the child’s ability to navigate social interactions throughout their lives.
