Young children’s language development starts from their very early age. Positive parent-and-child interactive quality closely linked to young children’s linguistic and social development. The aims of this study were to explore the parent-and-child interactions of new immigrant mothers and their 6-month infants, and to compare the contents of interactions between different cultural and national origins. The research findings included: the new immigrant mothers’ verbal communication influenced their interactions with infants. Most of the family dialogues presented their caring activities. However, the Chinese mothers tended to adopted more expressive way to convey their feeling or behaviors. The immigrant mothers from Southeast Asian countries adopted more short sentences with commends and order due to their limited vocabularies. The Southeast Asian immigrant mothers used very limited sentences and then they seldom had expressive sentences to the interacting situation. Their oral expressions tended to be meaningless and informal. The immigrant mothers less paid attentions to infants’ needs and showed more emotional responses due to their pressure at home. The following suggestions were provided: it could be better to encourage the Southeast Asian immigrant mothers to use their heritage language to interact with their children and therefore this could expand the dialogues. Secondly, we may train or teach the immigrant mother how to notice their children’s needs and to make proper responses. Thirdly, parent-and-child interactions are not only related to care but also empathy and emotional support.
