„Families stimulate children’s language development through various activities and interactions during infancy. Several factors have been suggested as being of particular relevance: the frequency of stimulating activities, such as joint picture book reading, singing songs, or telling rhymes to a child, and the overall quality of interaction behavior in parent-child interactions, especially how sensitively the caregiver responds to the child’s signals.“
