The aim of this study is to investigate communicative functions of repetition in children interaction. This study looks at how participants use repetitions to meet the communicative needs and maintain conversation. The results of this study indicate that children use repeated forms to convey the message, to maintain a conversation, to show response to the addresser, to create interaction etc. Those functions are viewed as the main contribution to coherence in child discourse. Due to the emphasis of kinship in Chinese culture, this study also shows repeated forms are often used by the younger child of participants in order to confirm the older child's utterance.
