• Exaggeration: It involves exaggerating facial expressions, gestures, and body movements to enhance engagement.

Purpose:

The purpose of Infant-Directed Speech is to facilitate language development, early communication, and social interaction in infants. It serves several important functions:

• Attention: The exaggerated features of Infant-Directed Speech help capture the infant’s attention and maintain their focus on the speaker.
• Emotion and Bonding: By using a warm, nurturing tone, Infant-Directed Speech helps create a positive emotional bond between the adult and the infant.
