Mother-Child (parent-child) Interaction theory is widely accepted that an infant’s development of self-regulation depends heavily on parents’ responsiveness to the infant’s emotional expression and needs. Mother-Child interaction plays a vital role in children’s language development. According to the theory, the interaction between parents and children helps children socialize, creates a family communication environment, and enhances the relationship values and skills. The positive quality of mother-child interactions and increased verbal responsiveness is essential in shaping a child’s literacy environment and language development. The first 3 years are especially the most intensive. When interacting with a parent, children learn social skills, such as sharing, cooperating, and respecting things of others. In addition, young children also learn to communicate and develop motor skills.
